Subtracting a number is the same as adding its opposite.
Use this understanding to complete each of the equations below.

answer:

1) 7

=2

2) (-7)

=-13

Step-by-step explanation:

so simply the two negatives would cancel eachother out so it would be -5 + 7 which is just 7-5 = 2 which is the same thing as -5 + 7 so your answer is 7 with a final answer of 2

then for the next one it’s the opposite so it would be -5 + (-7)

which then = -13
