Question

Subtract using a number line -4 - (8)

Answer 1

your answer will be -12

Answer 2

For this case we have:

We build a numeric line like the one shown in the attached figure.

We place the number -4.

As -4 you want to subtract 8, we run, from -4, eight spaces to the left. That way you get -12.

So, using a number line we have
`-4- (8) = - 12`

Answer:

`-4- (8) = - 12`
