Answer:

Here's one way to do it

Step-by-step explanation:

You  can use a number line for the subtraction of integers.

Subtracting a negative number is the same as adding its opposite; you move to the right on the number line.

The opposite of -8 is +8 , so

2 - (-8) is the same as 2 + 8.

Start at 2 and move 8 units to the right.

See the number line below.

2 - (-8) = 10
