Question

Susie is trying to calculate 7−(−3). She uses the subtraction algorithm and finds that the answer is 10. She is confused about why her answer is bigger than either of her original numbers since she is subtracting. How could a number-line model be connected to the expression 7−(−3) to help Susie understand why her answer of 10 is correct?(1 point)
