Math Vocab 4 Morgan

Algebraic Expression

A type of expression that contains one or more numbers, variables, and operation symbols (They CANNOT be solved to represent a single value)

Base

A number in an expression that is multiplied repeatedly

Coefficient

The number that is placed before (and multiplied) by the variable in an algebraic expression (For example, 27y + 12)

Constants

Numbers that never change in an algebraic expression (For example, 27y + 12)

Cubed

An expression where a base number is taken to the third power

Distributive Property

Multiplying a number outside parentheses by a group of numbers that are being added or subtracted For example, a(b+c) = ab + ac

Expanded Form

Writing out an expression using multiplication instead of an exponent

Exponent

The number in an expression that tells you how many times to multiply the base by itself (Also referred to as a power or index)

Evaluate

To solve

Factoring

The reverse of the Distributive Property (Parentheses are included instead of getting rid of the parentheses)

G.E.M.S.

Grouping Symbols, Exponents, Multiply/Divide (left to right), Subtract/Add (left to right)

Like Terms

Parts of an expression whose variables (and exponents) are the same (For example, 3d and -5d or 11y squared and 8y squared)

Numerical Expressions

A type of expression that contains one or more numbers and operation symbols (They CAN be solved to represent a single value)

Order of Operations

A collection of steps or rules such as P.E.M.D.A.S. or G.E.M.S. that can be helpful when evaluating a numerical expression

Properties

A set of math rules that are always true

Squared

An expression where a base number is taken to the second power

Substitute

To replace a variable with a number within an algebraic expression

Terms

Parts of an expression that are separated by a + or (The expression 9x2 + 2y 3 has three terms)

Variable

A symbol, such as x or y, that is used to represent an unknown value (27y + 12)
