And I don’t mean 2 + 2 is 4, I mean fractions,decimals and so on. I’ve been out of school for awhile and forgot all that stuff and I bombed the math part of the placement test at school so they put me in the lowest math class. The class is full but I figured I might buy the book they use and teach myself. Maybe I’ll be able to take the placement test again and get into a higher math class.
