An expression

• is an equation

• has an equal sign

• does not have an equal sign

• is how you feel

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

Variables are known as variables

• because they never change

• because their value can change

The pronumeral in the expression 7a - 8 is

• 7

• a

• - 8

• 7a

The pronumeral in the expression 9 - 3 x 7 + b is

• 9

• -3

• 7

• b

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
