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[tex]-4- (8) = - 12[/tex]
Answer:
[tex]-4- (8) = - 12[/tex]
