The distance between a number and 0 on a number line. Absolute value bars are usually represented with |x|.
An angle whose measure is less than 90 degrees.
A triangle whose angles all measure less than 90 degrees.
Addition Property of Inequality
For all numbers "a", "b", and "c", if a > b, then a + c > b + c and if a
Addition Property of Equality
Adding the same number to each side of an equation produces an equivalent equation. If a = b, then a + c = b + c.
Additive Identity Property
For any number "a" , a + 0 = 0 + a = a
Additive Inverse Property
For any number "a", a + (-a) = 0
An expression that includes one or more numbers and variables along with at least one arithmetic operation.
An algebraic expression or equation used to represent a real-life situation.
A step-by-step method for computing.
A figure formed by two rays that begin at the same point.
A measure of how much surface is covered by a figure.
For any numbers "a", "b", and "c", (a + b) + c = a + (b + c) and (ab)c = a(bc)
The sum of a set of numbers divided by how many numbers are in the set. Also called the mean.
Two perpendicular number lines used to locate points on a coordinate plane
