How to Simplify Expressions

Algebraic expressions are made up of letters and numbers. We call the letter the unknown. When a letter and number are together, such as 2b, we call this a term. When we simplify algebraic expressions we collect the like terms together.

Simplifying Expressions - Harder Examples

Check out the example below. Some terms contain more than one variable. The term “2a” is different to the term “2ab” for example. If a = 3, let’s say, when you substitute it into 2a the answer is 6. If we substitute a = 3 into 2ab, the result is 6b. b is unknown. When we add 5xy with 2xy the answer is 7xy. However if the expression is 5xy + 2x we leave the simplification as it is. We do not combine 5xy with 2x because they are different variables.
