to evaluate means to work out or figure the answer...

42--32=10...?

You would actually right this question like:

42 - (-32); this is because you are not supposed to have two of the same symbols next to each other in a math equation. It looks sloppy and can get confusing.

42 - (-32) is the same thing as 42 + 32 because there are two negatives, and if you have previously learned this, a negative and a negative will make a positive in math. It's like have 42 positive marbles, then adding 32 positive and negative marbles, and getting rid of the negative ones (subtracting a negative just like you are doing in the equation). When you do that, you take away the 32 negative marbles, and are still left with the 32 positive ones PLUS the other 42 positive marbles, and you will now have a total of 64 marbles.

So:

42 - (-32) = 64, and does NOT equal 10.
