Multiply and Divide Integers

Multiplying and dividing integers feels like multiplying and dividing whole numbers, but with one extra job: choose the sign. Once you know the sign, you only need your basic times tables and division facts to finish. The exact same sign rule covers both operations, so you only have to memorize it once.
