Algebraic ExpressionsAlgebraic ExpressionsObjective: To convert units of measure between the customary and metric systems.

Algebraic ExpressionsA numerical expression is a combination of numbers and operations.

For example,3 x 2 + 4 x 4

Algebraic ExpressionsAlgebraic expressions contain at least one variable and at least one operation.

e.g. n + 2

Algebraic ExpressionsA term can be a single number or variable or numbers and variables multiplied together and separated by addition or subtraction. e.g. 4x + 4

This expression has 2 terms.

Algebraic ExpressionsA coefficient is the numerical factor of a term that contains a variable.

e.g. 4x + 4

In this expression there is only one term that has a variable and the coefficient is 4.

Algebraic ExpressionsA term without a variable is called a constant.

e.g. 4x + 4 Constant.
