Marty is explaining to susan how to solve the following problem, -4 – (-5)
he told susan that to subtract an integer, add its opposite. which of following would be correct?
a. to subtract an integer, add its opposite; 4 + (-5) = -1.
b. to subtract an integer, add its opposite; 4 + 5 = 9.
c. to subtract an integer, add its opposite; -4 + (-5) = -9
d. to subtract an integer, add its opposite; -4 + 5 = 1

The correct answer is:

To subtract an integer, add its opposite; -4 + 5 = 1

Step-by-step explanation:

Marty is explaining to Susan how to solve the following problem, -4 – (-5)  

He told Susan that to subtract an integer, add its opposite.

We know that whenever we solve the two terms, first we multiply the signs.

It means that the negative sign outside the round bracket will be multiplied with the negative sign of -5

That is,

-4 - (-5)

By multiplying the signs we get the terms:

-4 + 5

=1

Thus the correct option is D
