JAY LENO: When you help your daughters with their homework, is there a subject you struggle with? PRESIDENT OBAMA: Well, the math stuff I was fine with up until 7th grade. But Malia is now a freshman in High School and I'm pretty lost. It's tough. Fortunately, they are great students on their own. And if something doesn't work I'll call over to the Department of Energy to see if they have a physicist to come over!
