Lesson 2.4 and 2.6 Multiplying and Dividing Real Numbers Goal: You will multiply and divide real numbers.

Rules for Multiplying Integers: Multiplying two numbers with the same sign will ALWAYS equal a positive number. ex. 4(8) = ___ ex. -9(-5) = ____ Multiplying two numbers with different signs will ALWAYS equal a negative number. ex. 4(-9) = ____ ex. -10(50) = ____

Find the product. You Try!

Properties of Multiplication: Property of Zero: The product of a number and 0 is 0. Identity Property: The product of a number and 1 is the same number.

Rules for Dividing Integers: Good News… Same as multiplying rules!! Dividing two numbers with the same sign will ALWAYS equal a positive number. ex. 28 ÷ 7 = ___ ex. -15 ÷ -3 = ___ Dividing two numbers with different signs will ALWAYS equal a negative number. ex. -16 ÷ 4 = ___ ex. 99 ÷ -11 = ___

Find the quotient. You Try!
