Question

I need to know 37-45 and show work

Answer 1

No problem! since 37 is smaller than 45, then your answer will be negative, so instead, switch the numbers around, making it 45-37. Now, just find the answer (8), and add a negative. So your answer is -8.

37-45=x
45-37= -x
45-37=8
47-35=-8

Answer 2

37-45= -8
The answer is a negative number
