Why do you think that when subtracting a negative number, in reality you are adding it? (For example: 1-
(-1) = 1+1=2)

See explanation

Step-by-step explanation:

When we have a positive number and a negative number, let's imagine it with a number line.

<0>

If we have the positive number 1:

<0--1>

And we want to subtract 1 from it, the number would move to the left

1 - 1 = 0

<0>

However, if we were to subtract a negative number, they are opposites. It can't move to the left because that's what a positive number does. The only other way to go: right.

1 + -1 = 2

<0--1--2>

Hope this helped!
