I know for a fact that when it comes to math, I'm pretty slow. Today was the first day of school, and I have a math assignment but I'm very confused. It's a fraction paper. One side was really easy for me but this side I'm just not getting.
-1 1/4 + -2 1/2 =
I keep getting -2 1/4, but there's a list of answers (in a different order) at the side of the paper, and my friend told me the answer was 3 3/4.
Can someone help me with this problem? I don't seem to understand what I'm doing wrong.
My work is
-1 1/4 + -2 1/2 = -3/4 + -3/2 = -3/4 + -6/4 = -9/4 = -2 1/4 (link)

-1 + -2 = 3 because two negatives equal a positive. -1/4 + -1/2 = -1/4 + 2/4 = 3/4 for the same reason. Put them together and you've got 3 3/4.
Hope you got that.
