Key concepts explained: the multiplication and division of integers.. . Our young presenter ventures fearlessly into the negative zone to learn how to add, subtract, multiply and divide positive and negative numbers. A variety of highly visual tools are presented in a fun format to help students make sense of the rules for integer operations.
