Term

Definition

Algebra

Algebra is the branch of mathematics in which letters and other general symbols are used to represent numbers and quantities in formulae and equations

Algebraic Expressions 

One or more algebraic terms separated by operating symbols this does not include an equal sign

Variables 

In algebraic expressions, letters represent variables. These letters are actually numbers in disguise

Coefficients 

Coefficients are the number part of the terms with variables

Constants 

Constants are the terms in the algebraic expression that contain only numbers. That is, they're the terms without variables

Real Numbers 

Real numbers describe real-world quantities such as amounts, distances, age, temperature, and so on

Rational Numbers 

We call the set of real integers and fractions "rational numbers."Rational comes from the word "ratio" because a rational number can always be written as the ratio, or quotient, of two integers

Irrational Numbers 

Some real numbers can't be expressed as a quotient of two integers
