Is it right? If not Please explain....
One of your answers shows subtraction; the other shows addition. How can that be?
I know C shows addition. I wasn't really sure about A,B or D cause they all show subtraction.
Yes, that's right. A, B, and D are correct.
I am confused. Aren't you supposed to do addition. I thought you do subtraction when you are trying to find the sum.
A negative and a positive is a negative.
