Algebraic Expressions - Day 1

Algebraic Expressions
Today we will answer these questions:

• what is an algebraic expression?

• what are the specific parts of an algebraic expression?

• what properties can I use to simplify expressions?

• what properties can I use to find equivalent expressions?
  

Let's look at an algebraic expression...

an algebraic expression consists of one or more variables, numbers and operations.

Multiple Choice

A(n) __________________ consists of one or more numbers, variables, and operations. 

• numeric expression
• term
• variable
• algebraic expression

There are 5 specific parts to an algebraic expression:

• terms

• variables

• coefficients

• constants

• operations
  

the term is a number and/or variable that is separated by addition or subtraction.

​

Terms

Multiple Choice

A(n) __________________ is a number and/or variable that is separated by addition or subtraction.

• variable

• term

• coefficient

• expression

the variable is a symbol, usually a letter that stands for an unknown number

​

Variable

Multiple Choice

Identify the variable in the algebraic expression.

5x + 13

• x

• 5

• 13

Multiple Choice

In the expression 3p + 4, what is the word for the number p?

• term

• coefficient

• product

• variable

Multiple Choice

A _____________ is a symbol, usually a letter that stands for a number. 

• coefficient
• algebraic expression
• variable
• term

the coefficient is the numerical factor (number being multiplied) of a variable term in an algebraic expression. Remember that when a variable is by itself the coefficient is 1.

​

• x² and x

• 2

• 2 and 1

Multiple Choice

A ___________ is the numerical factor (number being multiplied) of a variable term in an algebraic expression.

• term

• coefficient

• variable

• constant

the constant is the numerical (number) term in an algebraic expression.

​

​Constant
