The process of evaluating an algebraic expression means to find the value of an expression. Let’s take a look at the example:

Example:

x+3 = 5

To find the value of this expression, you need to substitute in a value for variable ‘x’. For this example, let’s say x = 2.

When we substitute that into the expression it becomes 2+3 = 5; So that is equal to 5.

Essentially, when evaluating an algebraic expression you are finding a number or many numbers by substituting in values given for variables and completing simple mathematical operations on those values until you have one answer. This is most commonly done using substitution but can also be done with other methods such as factoring and expansion.
