Multiplying Integers
• Multiply the absolute values of the integers.
• If both integers have the same sign, the product is positive.
• If they have different signs, the product is negative.

Henry multiplied two negative numbers. Franklin multiplied a negative and a positive number. Franklin claims his product is greater than Henry’s because both Henry’s numbers are negative and negative numbers are less than positive numbers. What would you tell Franklin? Explain.

The Identity Property of Addition says that the sum of any number and zero is equal to the original number.
a + 0 = a
The Zero Property of Multiplication says that the product of any number and zero is equal to zero.
a x 0 = 0
