Answer 1

Answer:

1. 7-5 =2

2. -7 + 5 = -2

3.-7 - 5 = -12

4. 7 - (-5) = 12

Step-by-step explanation:

#4 - The reason it's 12 is because the -5 is in parenthesis which means they want you to find the absolute value of the number and then add it. The absolute value of a negative number is positive.

#3 really you're adding 5 to -7.

#2 opposite of #3, you can think of it as subtracting 5 from -7.

3) -7-5 = -12
4)7 - (-5) = 12
