Back

terms

Front

parts added together in an expression that can be written as a sum

Back

coefficient

Front

number in a variable expression

Back

variable

Front

letter used to represent one or more numbers in an algebraic expression

Back

solve for a variable

Front

rewrite an equations an equivalent equation in which the variable ends up on one side and does not appear on the other side

Back

power

Front

expression used to abbreviate repeated multiplication of the same factor (power can be defined both as the whole figure or the exponent)

Back

linear equation

Front

equation that can be written ax + b = 0 ; a and b being constants and a is non-zero.

Back

Subtraction Property of Equality

Front

used to make equivalent equations; subtract the same number from both sides of the equals sign

Back

Addition Property of Equality

Front

used to make equivalent equations; add the same number to both sides of the equals sign

Back

compound inequality

Front

two simple inequalities joined by "and" or "or"

Back

linear inequality

Front

when in one variable could be written as any of the following where a and b are real numbers and a is non-zero number
ax + b < 0
ax + b > 0
ax + b </= 0
ax + b >/= 0

Back

like terms

Front

terms in an equation that have the same variable parts and can therefore be simplified

Back

reciprocal

Front

multiplicative inverse

Back

equivalent equations

Front

two equations with the same solution

Back

exponent

Front

the number of times the base is multiplied by itself

Back

base

Front

factor to be multiplied by itself in a power

Back

equation

Front

a statement of equality for two expressions

Back

Multiplication Property of Equality

Front

used to make equivalent equations; multiply both sides by the same non-zero number

Back

absolute value

Front

the distance a number is from 0 on a number line, represented by two enclosing lines

Back

Division Property of Equality

Front

used to make equivalent equations; divide both sides by the same non-zero number

Back

extraneous solution

Front

an apparent solution that must be rejected because it does not satisfy the original equation (a.k.a. it's wrong XD)

Back

identity

Front

a statement that equates two equivalent expressions
