I've been just eating very healthy, all organic, no sugar, white flour, nothing artificial. I'm being so incredibly strict... not a lot of meat!
I noticed there were so many people, especially women, who would come up to me having recognized me from TV and say, 'I heard you were a math person, why math? Oh my gosh, I could never do math!' I could just see their self-esteem crumbling; I thought that was silly, so I wanted to make math more friendly and accessible.
One of the most amazing things about mathematics is the people who do math aren't usually interested in application, because mathematics itself is truly a beautiful art form. It's structures and patterns, and that's what we love, and that's what we get off on.
A reciprocal of a fraction is found by flipping it upside down. If you want the reciprocal of a mixed number or a whole number, just convert it to an improper fraction, and then flip it!
