There's a question on the GMAC practice test that I had no idea how to do. I don't know how to upload it onto a thread, but it was an addition table that looked like this:
+ x y z
4 1 -5 m
e 7 n 10
f 2 -4 5
with border lines running across the top row and 1st column. You are supposed to solve for the value of m+n. Are columns and rows supposed to sum up or something?
