During the private Q-and-A session with Applie vice president Lisa Jackson, the former First Lady also discussed several issues, including diversity in tech, Stem education, innovation and leadership.
"We [in the US] have been teaching math and science the same way for too long," Obama said. "How do we get them to love these topics at [ages] 10 and 11?"
She said that the absence of girls and women in the so-called Stem fields has a deleterious affect on the tech industry.
"I'm very passionate about girls' education, and we still have a long way to go on equality and access," Obama stated.
"We have to teach young girls they are smart and can compete."
