I did have some problems with the other two levels, though. The most difficult one for me out of the three levels was the fractions. I think I had the most trouble with that one because some of the fractions did not have common denominators. I have yet to learn how to subtract fractions with unlike denominators in an easy and fast way. I eventually found out though because I looked online. The easiest way was to cross mulitply, and then add, and then add the denominators for the common denominator. I found that very easy and it also worked. I'm glad I learned how to do that because it is very helpful.
I didn't have much trouble with the decimals, expect that some numbers had me thinking for awhile. I think the reason why I had trouble was because there was more than one number and there was a decimal. But overall, I enjoyed playing that math game.
