Here's one way to do it
Step-by-step explanation:

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
