__Integers__: A member of the set of positive whole numbers and negative whole numbers and zero. Ex.1 2 3 and -1 -2 -3

__Scientific Notation__: A way to represent very large or very small numbers multiplied by the power of ten. Ex. 25,900,000,000,000

2.59 x 10 to the 13 power

__Factors__: A number that you can multiply that equals a product. Ex. 10: 1,2,5,10

__Multiples__: A multiple of a whole number is the product of that number and another whole number. Ex. 8: 8,16,24,32,40,48

__LCM__: (Least Common Multiple) Smallest number that is a multiple of all the numbers in a set of number Ex.8:8,16,24,32,40,48 The LCM is 8 because its the smallest. 2:2,4,6,8,10,12,14

__GCF__: (Greatest Common Factor) The greatest of the common factors that two or more numbers share Ex. 20: 1,2,4,5,10,20 The GCF is 10 because its he greatest factor. 30: 1,2,3,5,6,10,15,30

__Prime Factorization__: Breaking down a number into a product of all its prime number. Ex.

__Exponents__: A number or symbol, placed to the right of and above another number, symbol, or expression, denoting the power to which that number, symbol, or expression is to be raised. Also called //power//. Ex. 5 + //2//3 __Prime Numbers__ : A whole number greater than one with only two factors, itself and one. Ex. 1, 2, 3, 5, 7, 9, 11, 13, 17, 19, 23

__Composite Numbers__: A whole number greater than one with two or more factors. Ex. 4, 6, 8, 10, 12, 14, 16, 18, 20

Order of operations Parentheses Exponents Multiplication Division Addition Subtraction

__Decimals__: A multiple of a negative power of 10. Ex. 12.30 __Algebraic expressions:__ A mathematical phrase using operations and variables that are replacing numbers. Ex. y  × 12  × 2 __Numerator:__ The top number of a fraction Ex. The "x" is the numerator __Denominator:__ The bottom number of a fraction Ex.The "y" is the denominator __Mixed Numbers:__ A fraction that contains a whole number and next to it is the proper fraction. Ex. The 5/2 is the improper fraction and the 2 1/2 is the mixed number __Percents:__ A number out of 100 Ex. 45%

__sum__: The answer to an addition problem Ex. 4+5= 9 << the sum __difference:__ The answer to a subtraction problem Ex. 4 - 2 = 2 << the difference

product:   The answer to a mulitplication problem. Ex. 5    ×   5 = 25 << the product    __quotient:__ The answer to a division problem. Ex. 15  ÷ 3 = 5 << the quotient __factor pairs:__ Factor pairs are two numbers that make up a product. Ex. 2, 5 = 10

__variables:__ A letter representing a number. Ex. 6+9+y << the variable

__Equations:__ A problem that has an equal sign at the end and can be solved. Ex. 6+ 3 + 2 = 11 __absolute value:__ The number value of a real number that doesnt involve the sign within. Ex. |4| absolute value of 4
