-7+(5) find the sum
-2. Use the sign of the larger number which is 7.
just subtract the smaller digit frm the grater irrespective of signs and give the answer the sign of the grater digit.. so the answer is -2
that is what I thought but someone is trying to tellme that it is -12 but when adding differnet signs you subtract and keep the higher numbered sign right?
Think about it. You start with 0. You moved 7 space to the left. So you have -7. Now + mean move to the right. So your moving 5 time to the right. You will land on -2.|dw:1369498248886:dw|
