Find each difference. Example A: 9 - 17 Example B: -7 - 3
9 - 17 = 9 + (-17) -7 - 3 = -7 + (-3)
= -8 = -10
1.)-2 - ( -8 ) 2.) 4 - ( -11 ) 3.) -7 -6
4.) 15 - 2 5.) -7 - ( -1 ) 6.) 1 -9
Evaluate each expression. If a = -9, b = 4, and c = -5
7.) a - 8 8.) 10 - c 9.) b - 25
10.) a - b 11.) a + b - c 12.) a - ( -b ) + c
