Yes correct but pay attention to the negative numbers and make sure you add correctly

Answer 13

@breanna1999 okay, so how do you work with the negative number?

Answer 14

You have a positive 4p plus a negative 7p. You can rewrite this as 4p-7p. If you put this into a calculator you would get -3p or you could draw a number line and place a point on 4 and go backwards 7 spaces
