Integer Rules

Adding, Subtracting, Multiplying, and Dividing

Adding

When adding, if the signs are like, you add the integers and stay with the sign.


If the signs are unlike, subtract the integers and stay with the sign of the higher integer.

Subtracting

When subtracting, if the signs are the same, you add both integers and stay with the sign.


If the signs are different, you subtract and stay with the sign of the bigger number.

Multiplying

When multiplying integers, if the signs are like, you multiply both integers and the answer stays positive.


If the integer's signs are unlike, multiply both numbers, and the result will always be negative.

Dividing

If you are dividing integers, if both integers have like signs, divide both numbers and the result is positive.


However, if the integers are unlike, divide and the result is negative.
