What is the rule when adding integers? For example: 13 + (-1) =

• If the signs are the same, add and keep the sign. If the signs are different, subtract and keep the sign of the larger whole number.

• A negative times a negative equals a positive.

• Same, Change, Change

• A negative divided by a positive equals a negative.

What is the rule when subtracting integers? For example: 13 - (-12) =

• Keep the signs and add

• Same, Change, Change

• A positive times a negative is a negative

• Same, Same, Change

Re-write the equation below to show what it would look like after applying the rule for subtracting integers (Same, Change, Change):

-10 - 5
