Middle Sister thinks so, anyway.
TheDad is checking her math homework. (Division of homework in our house: I help with English, Spanish, history and religion. TheDad helps with math, history and science.)
TheDad is really good at math. He graduated college with a degree in meteorology, which required a lot of calculus. Now he programs computers for a living, so he uses math every day.
So Middle Sister didn't have a leg to stand on when she tried to defend herself by saying, "Dad, are you sure you know the Order of Operations?"
