- and + are the same operation. / and * are the same operation. Well, they're
inverse, but to be inverse they must use the same stuff (ya know, like to be
opposites words must describe the same thing--hot and cold). -x = +(-x) and /x =
*(1/x). It wouldn't make any sense to do multiplaction then subtraction then
division then addition, or something like that.
