We all know that one person, the one who, when it comes time to split the bill at dinner, responds "I'm not a math person" and whips out their cell phone calculator.
A nonprofit online program, Khan Academy, wants to make sure the kids of tomorrow learn math and other subjects at their own pace.
"It's like having a personal tutor for your kids to help them through their homework, to help them understand concepts, that's completely free," said Head of Marketing Monica Tran.
The program is in use by 15 million people, including a Phoenix middle school whose students were several years behind.
"Thirty-eight of their seventh and eighth graders have not only caught up, but have earned high school credit," said Tran.
One of the program's strengths is allowing students to move at their own pace, something schools sometimes can't accommodate.
"We create these pillar programs so you're child can advance as far as he or she would like so no one's bored and people always feel they can advance at their own pace," said Tran.
