question

Subtract:

^–1 − ^–1 =

key idea

Subtracting a negative is the same as adding a positive.

You can add numbers in either order.

solution

Change the negative sign and the minus sign to a plus sign:

^–1 − ^–1 = ^–1 + 1

Now you are adding, so you can switch the order of the numbers:

^–1 + 1 = 1 + ^–1

Change the negative sign to a subtraction sign:

1 + ^–1 = 1 − 1

Subtract:

1 − 1 = 0

So:

^–1 − ^–1 = 0
