math

I have always kind of wondered how whoever makes worksheets put exponents on numbers on the worksheets. I'm sure the 1-4th or 5th grades don't have to worry about that but the 1st grade teachers have it very easy. 1+2=___  2+5=___ 5-2=___. Easy, but then again how do you put the dots to trace over the number to teach you. So they must have some special software for that. Oh yeah, in case you didn't know, he answers to those math problems are: 3, 7, and 3.
