adding a negative number is the same as subtracting a positive number. This question is the same as 10.5-8.3
Answer:
Step-by-step explanation:
1) 5 - [-5] = 5 + 5 = 10
2)8 - 13 = 8 + (-13) = -5
3) 12 +(-3) = 9
4) x + (-7) = 5
x - 7 = 5
x = 5 + 7
x = 12
We need to add 12 to (-7) to get 5
5) 7 - x = -5
7 = -5 +x
7 + 5 = x
12 = x
We need to take away 12 to 7 to get (-5)
6) 7 - (-10) = 7 + 10 = 17
