Add the positive numbers.

Then add the negative numbers.

Subtract the negative sum from the positive sum.
if you add a negative number, it is the same as subtracting. if rewritten as
96-100+773-297+10-251
then it is much simpler to look at.
when put in a calculator you end with an answer of 231
dang, she answered before me. Teacher got typing skills.
