Chapter 2 Whole Number Multiplication and Division
* 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.
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).
