Question

-20+8 on a number line

Answer 1

-12

Explanation:

You star at 0 on the number line

Negative numbers move to the left

Positive numbers move to the right

From 0 you move 20 units to the left and you land on -20

Once you are on -20 you need to move 8 units to the right because 8 is positive

As result you land on -12
