# Chapter 2 Whole Number Multiplication and Division

• Chapter 2

Chapter Objectives:

* Patterns can be used to help you multiply and divide numbers.

* Numeric expressions can be simplified using the order of operations.

* Multiplication and division can be used to solve real-world problems.

Vocabulary:

Product - The result of multiplying two or more quantities. The answer to a multiplication problem.

Factor -A whole number that divides exactly into another number. Ex: 2 X 9 = 18. 2 & 9 are factors of 18.

Base (of an exponential expression) - The number being multiplied.

Exponent - A number that tells how many times the base is used as a factor.

Square (of a number) - Multiplying the number by itself. A number that is the product of two equal factors. Ex: 25 is the square of 5.

Cube (of a number) - Multiplying the number as a factor three times. Ex: 27 is the cube of 3, because 3 X 3 X 3 = 27.

Quotient - The result (answer) in a division

Dividend - The number that is being divided.

Divisor - The number that the dividend is being divided by.

Remainder - The number that is left over when a divisor does not divide the dividend exactly.

Numeric expression - An expression that contains only numbers and operation symbols (with no equal sign).
