# Algebra Help: Basic Vocabulary

05/20/2015
Although it’s mathematics, algebra is a sort of language in its own sense. Introducing letters into long and confusing equations can make algebra a difficult subject for any student. To help make things a little easier, our math experts at The Tutoring Center of Franklin Park have compiled a list of some basic algebra vocabulary to know before trying to understand full algebraic equations.

Real Numbers: A real number can be thought of as any point anywhere on the number line, no matter how many decimals it has. Any point anywhere on the number line.

Integers:  All of the negative and positive whole numbers, including zero.
Ex: ......-3,-2,-1,0,1,2,3......

Rational Numbers:  A number that can be expressed as a fraction or ratio of 2 integers, as long as the denominator does not equal zero.
Ex: 1, 1/3, 55/100, 100/50, etc.

Irrational Numbers:  A number that cannot be written as a fraction because it has an infinite amount of decimals with no definite ending.
Ex: Pi is the most famous irrational number because there is no way to write it as a fraction.π = 3.1415926535897932384626433832795 (and A LOT more...)

Variable: A symbol, usually a letter like x or y, for an unknown number. There can be multiple variables to each equation.
Ex:  in 3x + 2y = 12, x and y are variables.

Constant: Something with a fixed value. In Algebra, a constant is a number on its own, or sometimes a letter such as a, b or c to stand for a fixed number. If it is not a constant it’s a variable.
Ex: in "z + 7 = 16", 7 and 16 are constants, while z is the variable.

This is just a short list of vocabulary to help algebra students at the very beginning of learning the subject. For one-to-one instruction in algebra or any subject, call us today at (732) 419-3813 for information about specially designed academic programs in Franklin Park.
