square root

Front

- raise to the second power

Back

product

Front

coefficient

Front

the number multiplied by a variable in a term - the "2" in "2xy^3"

Back

multiplicative property of zero

Front

states that any number multiplied by zero is zero

inequality

Front

a comparison of two expressions that uses one of the symbles <,>,=

term

Front

a number, a variable, or a product of numbers and variables

Back

zero exponent

Front

when the exponent is raised to the 0 power, it is always 1

Back

linear equation

Front

an equation with solutions that lie on a straight line when graphed, may be written as y = mx + b where m is the slope and b is the y-intercept

Back

exponent

Front

a mathematical notation indicating the number of times a quantity is multiplied by itself

Back

whole numbers

Front

all the counting numbers and zero {0,1,2,3,4,5...}

Back

linear measurement

Front

the distance between two objects, a straight-line measurement of distance (inches, feet, yards, miles, meters)

Back

irrational numbers

Front

a number represented by a non-repeating, non-terminating decimal - like pi or the square root of 2

Back

quotient

Front

the answer to a division problem

Back

factor

Front

a number multiplied by another number to find a product

Back

coordinate plane

Front

a system of intersecting horizontal and vertical number lines, used to locate points

Back

graph of an equation

Front

the set of all points (x, y) that are solutions of the equation, that make the equation true

Back

area

Front

the measure, in square units, of the inside of a two dimensional plane figure.

Back

equation

Front

an algebraic sentence that has an equal sign

Back

grouping symbols

Front

parentheses, brackets, braces, and vinculums used to make the order of operations clear: {[( )]} and /

Back

like terms

Front

terms in an expression that have exactly the same variables with the same exponents - in "4xy^2 + 3xy + 2xy^2", 4xy^2 and 2xy^2

Back

quadrants

Front

the four sections of a coordinate plane labeled counterclockwise I, II, III, IV

Back

associative property

Front

states that the way in which numbers are grouped does not change the sum or the product: (1+2) + 3 = 1 + (2+3)

Back

percent

Front

the ratio of a number to 100; means "per hundred"

Back

order of operations

Front

the order in which operations in an expression should be performed: PEMDAS

absolute value

Front

the distance between a number and zero on a number line

Back

proportion

Front

an algebraic sentence that states that two ratios are equal: 2/3 = 4/6

Back

expression

Front

mathematical phrase containing numbers, variables and/or operations: 2 + 3(4x+ 5)

Back

perimeter

Front

the total distance around a figure

Back

commutative property

Front

states that the order in which numbers are added or multiplied does not change the sum or the product: (1+2) + 3 = 1+(2+3)

Back

reciprocal

Front

a pair of numbers whose product is 1: 2/3 and 3/2; 7 and 1/7

Back

sum

Front

the answer to an addition problem

Back

parallel lines

Front

lines that have the same slope but different y-intercepts, they never intersect

Back

identity property

Front

describes the results of adding the number zero to another number or multiplying a number by one - the results are identical

Back

ordered pair

Front

two numbers, such as (2,3) that name a point on a grid

Back

integers

Front

made up of the counting numbers {1,2,3,4...), their opposites {-1,-2,-3,-4...}, and zero {0} irrational numbers:a number represented by a non-repeating, non-terminating decimal - like pi or the square root of 2

Back

Front

when you replace each variable with a number, then follow the order of operations rules

Back

function

Front

a mathematical relation such that each element of one set is associated with at least one element of another set
