When multiplying integers:

If the signs are the same, the product is positive

If the signs are the different, the product is negative

Example:

Determine each product

5 × 6 =

-8 × -3 =

-2(9) =

8(-3) =

2(-5)(-6) =

-1 × -3 × -4 × -6=

When three or more integers are multiplied

• The product of an even number of negative numbers is positive.

• The product of an odd number of negative numbers is negative.

Example:

Multiply

a) (-2)(-3)(-5) =

b) (-1)(-5)(-2)(-3) =

If the signs of the two integers are the same, the answer is positive.

If the signs of the two integers are different, the answer is negative.

The rules for multiplying integers are:

When we multiply two positive integers, we get a positive integer.

When we multiply two negative integers, we get a positive integer.
