Statements that are true for any number.
An expression that contains sums and/or products of variables and numbers.
The four regions into which the x-axis and the y-axis separate the coordinate plane.
The distance a number is from zero on the number line.
The whole numbers and their opposites.
A number that corresponds with a point on a number line.
The multiplicative inverse of a number.

In repeating decimals, the line or bar placed over the digits that repeat.
Two numbers whose product is 1.
The symbol used to indicate a non-negative square root.
A method of writing or displaying numbers in terms of a decimal number between 1 and 10 multiplied by a power of 10. 5,000,000=5.0 x 10^6
A number that can not be expressed as a quotient of two integers. The divisor cannot be zero.
An expression that is a number, variable, or a product of numbers and/or variables.
Parts of congruent or similar figures that match.
A comparison of two numbers by division.
A ratio of two measurements having different units.
A drawing that is used to represent an object that is too large or too small to be drawn in actual scale.
The process of including units of measurement when computing.

The amount the price of an item is increased above the price the store paid for an item.
The amount by which the regular price of an item is reduced.
percent of change
The ratio of the increase or decrease of an amount to the original amount.

A term without a variable.
A monomial expressed as a product of prime numbers and variables where no variable has an exponent greater than one.
greatest common factor
The largest factor two or more numbers have in common.
Each part of an algebraic expression.
Expressions that contain the same variables to the same power, such as 2n and 5n or 6xy and -4xy.
An algebraic expression in which the variable is raised to the first power.
The variable in a relation with a value that depends on the value of the independent variable. (y)
To multiply a sum by a number, multiply each addend by the number outside the parentheses. a(b+c)=ab+ac
Operations that undo each other, such as addition and subtraction.
An equation that is true for any value of the variable.
A value for the variable that makes an equation true.

system of equations
A set of two or more equations with the same variables.
The ratio of the rise, vertical change, to the run, or horizontal change.
A function is a special relation in which each element of the domain is paired with exactly one element in the range.
vertical line test
If any vertical line drawn on the graph of a relation passes through no more than one point on the graph for each value of x in the domain, then the relation is a function.
A linear equation in the form y=mx+b, where m is the slope and b is the y-intercept.
