Random math thought of the day: I cant remember the last time I set up a long division problem. Or division by fractions by inverting and multiplying... or moving the decimal of the divisor prior to long dividing. I wonder what moving a decimal, or inverting a fraction actually has to do with math. Outside of the classroom, Ive never done it that way... besides... with smart phones, cash registers and computers, I dont think I will ever need to.
