Parts of an Algebraic Expression

Mrs. Shurer

Numbers, letters, and operators (+, -, x, /) grouped together to represent a value.

​

An expression is a problem without an equal sign.​

​

​Some text here about the topic of discussion.

Expression

Multiple Choice

Which of the following is not an expression?

• 8a + (-9)

• -17 - 10

• 5x + 10 = -15

• 12 + (-5f)

Each piece (amount seperated by an operator) of an expression is called a term.

​

​

Terms

When determining if the term is positive or negative, use the sign in front of the term.

​

+ means the term is positive

​

​- means the term is negative

Terms

Multiple Choice

How many terms does the following expression have?

11x + 5 - 8x + 10 - x

• 4

• 5

• 3

• 2

Multiple Choice

How many terms are in the expression
3x + 2y + z

• 5
• 2
• 4
• 3

Expressions are made up of variable terms. Variable terms are terms with a variable in them.

Multiple Choice

Identify the variable terms in the expression below:

7a - 14 + 8a + 9

• 7a, 8a

• 14, 9

• a

• -14, 9

Each variable term has a coefficient.

​

The coefficient is the number attached to the variable by multiplication.​
