Which number line best shows how to solve -6 - (-8)?

-6 - (-8) = 2.

Your number line might have a bubble at 2. Or it may show movement 8 units to the right of -6. Whatever it is, you should end up at the value of 2.

Step-by-step explanation:

We don't see a number line, but I can still show how to solve.

-6 - (-8) is the same as doing negative six plus negative one times negative 8. Or in number terms it would look like:

-6 + (- 1(- 8))

In the order of operations -- PEMDAS -- we do parenthesis first.

- 1( - 8) = 8, so we simplify by plugging this value back into the equation:

-6 + 8

-6 + 8 is the same as 8 - 6.

8 - 6 = 2

Your answer is 2.
