Algebra Definitions

The sum of the exponents from all the variables in ONE term.

An expression is made up of

• pronumerals

• operators

• terms

• all of the above

An expression can be represented as

• 3m

• 4a + b

• 3 + 7 = 10

• x

A variable is represented as

• a letter

• a number

• an operator

• an equal sign

The letter x in the expression 8x - 79 is known as

• the value of x

• the variable

• the constant

• the coefficient

When a term doesn't show the operator, for example 3y, it means

• 3 x y

• 3 + y

• 3 - y

• 3 ÷ y

The number in front of a pronumeral is known as

• a constant

• a coefficient

• a term

• a number

The coefficient in the term 4g is

• 4

• g

• 4g

• 1

The coefficient in the term 45t is

• 45

• t

• 45t

• 1

The coefficient in the term -5t is

• 5

• -5

• y

• -5t
