Johnny Depp is hopeless with modern technology.
The 50-year-old actor - who has children Lily-Rose, 14, and Jack, 11, with former partner Vanessa Paradis - says his kids have learned not to ask him for help with their homework because he can only advise on music or history.
He said: "As far as technology... let me put it to you this way.
"My kids are smart enough to not come to me for any questions about the computer, even homework for that matter.
"Unless it's got to do with history or the future or music, I'm good.
"If it's math and all that, I'm down the road."
The 'Transcendence' star also admitted one of the "best experiences" of his life was cramming into an electric Tesla car with its founder Elon Musk, director Wall Pfister and co-stars Paul Bettany and Rebecca Hall - but their fun was cut short after they were stopped for speeding.
Johnny is quoted by The Sun newspaper as saying: "I had one of the best experiences I've ever had. The director introduced me to Elon Musk at Tesla. He came and visited the set and we had a ride around in his car but then the police pulled us over.
"We had a first - maybe the first -Tesla jam. I was in the front seat while Paul Bettany was sitting on my lap. Rebecca and Wally were in the back. Elon was driving and we were pulled over speeding."
While the 50-year-actor and his peers found the incident hilarious, he claims the policeman wasn't amused.
He added: "Elon had a good sense of humour about it. The cop did not. He needed a humour chip. But it was a good time, nonetheless."
Tesla are renowned for their fully electric luxury sportscars with the Tesla Roadster able to accelerate from zero to 60 mph in under 4 seconds with top speeds of up to 125mph.

Penélope Cruz could be set to star in the next James Bond film.
The 39-year-old actress is reportedly in the running to play the spy's lover in the upcoming next instalment, which will be a follow up to 'Skyfall' which starred Cruz's husband Javier Bardem as the villainous Silva.
Director Sam Mendes is reportedly keen to get the brunette beauty to star alongside current Bond actor Daniel Craig, who will play the super-spy for the fourth time next year.
A source told The Sun newspaper: "Bond bosses have been chasing her [Cruz] since Daniel became 007 in 2006. But schedules and her pregnancies meant it never materialised."
Cruz - who has 3-year-old son Leonardo and 9-month-old daughter Luna with Bardem - would follow in the footsteps of actresses including Halle Berry and Gemma Arterton to become a 'bond girl' and would also star alongside 'Skyfall' actors Ralph Fiennes and Naomi Harris.
However, the production team behind the film have so far made no comment as to whether they have approached Cruz for the role.
The source added: "At this stage no one at Sony will confirm it."
'12 Years a Slave' star Chiwetel Ejiofor has been tipped to play the main "baddie" in the film with Swedish beauties Ida Engvoll and Disa Ostrand already having completed screen tests to play extra love interests.
Filming is expected to begin in November with a release date of October 2015.

Simon Cowell will want a baby daughter next, according to Amanda Holden.
The 54-year-old music mogul welcomed his first child, son Eric, with Lauren Silverman in February and his 'Britain's Got Talent' co-star predicts he will want another child.
Amanda recalled Simon's sweet demeanour around her own daughters, Lexi, eight, and Hollie, two, whom she shares with husband Chris Hughes.
She said: "Simon was so cute when Hollie sat on his lap and shared a biscuit with him. Now when she sees Simon on TV, she calls him 'My Simon'. I think Simon will have more children - he'll want a girl next."
Amanda, 43, also admits she never thought she'd see the day Simon became a father.
She added to Closer magazine: "If a fairy had come along and said, 'Simon will be cradling a son this year', I would have laughed in its face. He has softened so much since he became a dad.
"I think Simon thought children and families weren't for him, but he is so happy. Simon brings Eric on set at 'BGT' and he's adorable. He has Simon's lips. He's such a good baby!"

'The Voice' winner Jermain Jackman wants to name his debut album 'Genesis'.
The 19-year-old London singer was crowned the winner of the show earlier this month, after beating finalists Sally Barker, Christina Marie and Jamie Johnson, and has revealed plans for his first record, which is inspired by the Bible.
He told BANG Showbiz: "We're just collecting songs and working with producers, we're striking while the iron is hot.
"I've very religious and I want to call my first album maybe 'Genesis' or something. It's the beginning of the Bible, a beautiful, wonderful and influential story.
"It's the beginning of something special and my first album is the beginning of an epic journey [for me], I want to acknowledge that biblical term."
The singer and Labour party activist is "in talks" with coach will.i.am for him to produce the album but insists it's "early days", although he is hopeful original material will feature on the new record.
He added: "I love song-writing and I'd love there to be original material on the album. I write songs at home with my twin sister, we write rhymes, if I get a flash of inspiration, I'll wake up with a melody in my head and I'll get my phone out and record it."

Kim Kardashian is reportedly taking her personal trainer on her honeymoon.
The 'Keeping Up With The Kardashians' star, who is expected to tie the knot with fiancé Kanye West in Paris next month, has been working hard to get in shape for the wedding and is said to have asked her trainer Gunnar Peterson to travel with them to Hawaii as she doesn't want to let herself go.
A source told the Daily Star newspaper: "Kim has paid for Gunnar to come along so she can work out while she's away on her honeymoon.
"Kim doesn't feel happy when Gunnar's not around as she loses her willpower so quickly.
"She doesn't want to undo all her hard work and pile on the pounds on the honeymoon."
The 33-year-old star got engaged to her rapper fiancé, 33, last October following the birth of their daughter North, and he's said to be more than supportive of her plans to carry on her fitness regime.
The source added: "Kanye totally gets it, he's completely supportive of Kim's efforts to lose the baby weight and get in shape for the wedding.
"North will stay with Kim's family and her nanny.
"Kim and Kanye want time away from parental duties as it's important for them to spend time alone as a couple."
Meanwhile, it's been revealed that Kim has not yet sent out the invitations for her nuptials, as she wants to keep the location a secret.
A source told HollywoodLife.com that 90 guests will soon receive a card printed with "a date and Paris" and will only find out where the couple will exchange vows when they check in to their chosen hotel in the city.

Stars paid tribute to late actors Paul Walker and Philip Seymour Hoffman at the MTV Movie Awards in Los Angeles last night (13.04.2014).
Jordana Brewster and Vin Diesel took a moment to remember their 'Fast and Furious' co-star Paul Walker, who died in a car crash in November last year at the age of 40, while on stage at the Nokia Theatre.
Jordana said: "I was lucky enough to work with him over the last 15 years and witness the generosity of his heart every day I was with him.
"He was humble, he thought about others. Whether you knew Paul for five minutes or were a close friend, he made you feel like the most important person in the world."
Following an on-screen tribute, which showed footage of Paul's film career and humanitarian efforts, Vin Diesel also honoured his friend.
He said: "The world saw his magic on-screen, the world saw his philanthropic endeavours, yet I wish the world could've seen how special a brother he was."
Meanwhile, Josh Hutcherson took to the stage to accept the Movie of the Year Award on behalf of the entire 'Hunger Games: Catching Fire' cast and after thanking the crew and fans he spoke about how excited his co-star Philip would have been to receive the prize.
Speaking to the audience, he said: "It was so cool to have Philip in our movies. He's one of the actors who I've looked up to my entire life.
"I know if Philip were here he would think this was really cool.
"We think about him everyday on set, so wherever he is, this goes out to him, too."
Philip, 46, died from an apparent heroin overdose earlier this year whilst in the middle of filming for the remaining 'Hunger Games' sequels in which he plays Plutarch Heavensbee.

Ellen Page honoured her "hero" Laverne Cox at the 25th Annual GLAAD Media Awards on Saturday night (12.04.14).
The 'Juno' actress, who revealed she is gay in February, credited the transgender 'Orange Is The New Black' star for inspiring her to come out before she presented her with the Stephen F. Kolzak award, for "making a significant difference in promoting equality for the community," at the star-studded ceremony at the Beverly Hilton Hotel in Los Angeles.
The 27-year-old star said: "Many of you know that I officially came out on Valentine's Day, and one of the best things that came from that is to publicly show support for the people who I admire and give me courage. And I'm here to do just that tonight for one of my hero's Laverne Cox."
'Inception' star Ellen admitted she was scared to open up about her sexuality for a long time when she announced she was gay at Human Rights Campaign's Time to Thrive event in Las Vegas earlier this year.
She said at the time: "I'm here today because I'm gay. And because maybe I can make a difference - to help others have an easier and more hopeful time.
"Regardless, for me, I feel a personal obligation and a social responsibility. I also do it selfishly, because I am tired of hiding and I am tired of lying by omission. I suffered for years because I was scared to be out.
"My spirit suffered, my mental health suffered and my relationships suffered. And I'm standing here today, with all of you, on the other side of all that pain."

Kate Upton wants to be a positive role model for curvy girls.
But the Sports Illustrated mode, who has made an estimated $4 million from her curvy figure over the past three years, admits she thinks her life would be "so much easier" if she has smaller breasts.
The 21-year-old 'The Other Woman' star told the UK's The Sun on Sunday newspaper: "I wish I had smaller boobs every day of my life as I would love to wear spaghetti tops braless or go for the smallest bikini designs.
"Every single day I'm like, 'Oh man, it would be so much easier', especially if people didn't constantly bring them up.
"If I could just take them off like they were clip-ons..."
But the blonde beauty insists that despite not being entirely happy with her famous figure, she is determined to embrace them and wants to be a positive role model for young girls.
She said: "I know I say I wish I had smaller boobs -- and that's true because at least twice a day I wish that. But the grass is always greener, as they say!
"I love my boobs and I'm proud of my size. That's an important message to young girls -- love who you are.
"It's so easy to feel negative about yourself and it is totally self-destructive. If you can only love and accept who you are you will be a lot happier."

Nick Carter's wedding was filmed for a reality TV special.
The Backstreet Boys star tied the knot with Lauren Kitt in Santa Barbara, California on Saturday (12.04.14) and fans will get a chance to watch their "emotional" big day later this year.
An eyewitness also told UsMagazine.com: "At the end of the ceremony they shared the longest wedding kiss I've ever seen. A full minute later they were still kissing. They seem crazy in love and thrilled to be married. You could feel the love bursting out of them."
The happy couple exchanged vows under an alter of white roses and hydrangeas with purple accents in front of guests, including the 34-year-old star's bandmates Howie Dorough, Brian Littrell and AJ McLean, whose daughter Ava was a flower girl.
The 'Everybody' hitmaker wrote his own vows and as he read them to his bride, she "reached out and put her hand on his chest."
Another source said: "Lauren held Nick's hand and dried tears from her eyes."
Fitness expert and aspiring actress Lauren, who wore a white strapless gown, carried a bouquet of white garden roses, peonies, and anemones, arranged by Petals LA, and vintage wood lanterns lined the rows of mismatched wooden chairs.
Production company Bischoff-Hervey Entertainment first began shopping around a half-hour documentary about the couple's wedding to cable networks in the US in March 2013, just one month after they got engaged, but it is not yet known which network will broadcast the show.

Gwen Stefani made her first public appearance at the Coachella Valley Music and Arts Festival since giving birth to her third child.
The No Doubt hitmaker, who welcomed son Apollo into the world on February 28, debuted her slim post-pregnancy figure, as she joined Pharrell Williams to perform her hit 'Hollaback Girl' during his set on Saturday night (12.04.14).
The blonde beauty, who also has sons Zuma, five, and Kingston, seven, with husband Gavin Rossdale, received a warm welcome from the new 'The Voice' USA mentor, who introduced her to the crowd, saying: "The name of my album is called 'Girl' and I can tell you right now there's only been one, incredible, historical, most important, incredibly talented, f**king awesome, rad girl in the world."
Clearly delighted to be back on stage, the 44-year-old blonde beauty later tweeted: "Feels good to be out of the cave #Cochella2014 @Pharrell gx"
The producer and singer's star-studded set also featured cameos from Snoop Dogg, as they performed their hits 'Beautiful,' and 'Drop It Like It's Hot,' Nelly for his track 'Hot in Herre,' and P. Diddy and Busta Rhymes for 'Pass the Courvoisier.'
But the 'Happy' hitmaker, 40, admitted he struggled to cope with the dust at the Empire Polo Club in Indio, California.
He said: "You don't even understand how hurt my feelings are right now that I'm losing my voice because of all this dust, because we really had something special planned for you.
"I really had some crazy s**t planned for you guys, but I'm just going to go for it anyways."

Naomi Campbell has a girl crush on Jennifer Lopez.
The British supermodel is a huge fan of the 'I Luh Ya Papi' hitmaker and is very proud of her success.
Asked who she admired, the 43-year-old beauty told E! News: "I have to say Jennifer Lopez because she's so beautiful and so stunning. I'm a huge fan. Great friend and a huge fan."

The 'The Face' star said: "She deserves it. I love Jennifer. I think she's an amazing singer, actress, designer, mother."
Accepting her award, the 'American Idol' judge opened up about her special relationship with her aunt Marisa, who is gay.
She said: "I've always felt a tremendous love from the LGBT community and the LGBT community has always supported me and returned that love. Marisa was my cool aunt. She was my mom's older sister and she lived in New York City. I lived in the Bronx and she lived in Manhattan, it was like worlds away! She wanted to be an actress and I always wanted to be like her. Marisa grew up gay in a time when it meant life could be very difficult and that her struggles were mostly kept to herself."

Debbie Rowe is furious with Michael Jackson's brothers for accusing her of abandoning her children for money.
The former nurse - who was married to the late 'Thriller' hitmaker for just under three years until October 1999 and had children Prince, 17, and Paris, 15, with him - was criticised by his siblings Tito, Randy, Jermaine, and Jackie Jackson for asking to be made her children's legal guardian and take responsibility for their brother Blanket, 12, who was born via surrogate, as she thinks their grandmother, Katherine Jackson, is too old to care for them properly.
A source told gossip website TMZ.com that Debbie, who began rebuilding her relationship with her children after Michael's death in 2009, wasn't surprised by the attack but insists she never turned her back on Prince and Paris, as Michael regularly called her for parenting advice.
Michael's siblings hit back at Debbie on Friday (11.04.14), saying: "[The children] are well loved and well taken care of. We are quite taken back [sic] that Ms. Rowe has decided now to enter their lives, after she abandoned her children many years ago for money."
But she claims Michael often accused his brothers of sponging off him and he thought Janet Jackson was the only one of his siblings with talent.
While she likes Katherine, Debbie wants the children to live on her horse ranch in Palmdale, California, as she believes they have no proper supervision.
She thinks the Jackson brothers are merely worried that they won't have access to $50,000 monthly child support from the Michael Jackson estate if she secures custody.
Debbie recently confirmed she is engaged to her long-time friend Marc Schaffel, who worked with Michael on his charity single 'What More Can I Give' in 2001.
