PROPERTIES OF MULTIPLICATION

OBJECTIVES:

AT THE END OF THE LESSON THE LEARNER SHOULD BE ABLE TO:

1. illustrate the property of multiplication that any number multiplied by one (1) is the same number;

2. illustrate the property of multiplication that zero multiplied by any number is zero;

3. illustrate the commutative property of multiplication; and

4. illustrate the associative property of multiplication.

COMMUTATIVE PROPERTY OF MULTIPLICATION

This shows that changing the order of the factors does not change the product.

COMMUTATIVE PROPERTY OF MULTIPLICATION

EXAMPLE

ASSOCIATIVE PROPERTY OF MULTIPLICATION

Shows that changing the grouping of factors does not change the product

ASSOCIATIVE PROPERTY OF MULTIPLICATION

EXAMPLE

PARENTHESES

() are grouping symbols

IDENTITY PROPERTY OF MULTIPLICATION

This shows that the product of any number and 1 is the number itself.

IDENTITY PROPERTY OF MULTIPLICATION

EXAMPLE
