What are Like Terms?

Mathematics has many complicated terms that make it difficult for us to solve mathematical problems. So, we need a concept to make it easier for us to solve these problems. One of them is "like terms." What's that?

Like terms are terms with the same variables and exponents. To solve math problems with like terms, you need to combine like terms which are used to group like terms in an equation.

Like terms use the concepts of variable, exponent, and coefficient. The variable represents a letter. Meanwhile, the exponent is how many times the term must be multiplied. Although similar terms must have the same variables and exponents, their coefficients can be different. Examples of like terms are as follows.

• 7x, 2x, 5x

In this example, all the variables are x. So, 7x, 2x, and 5x are like terms. Meanwhile, the exponent is 1 because x has an exponent of 1. However, they have different coefficients. In the example above, 7, 2, and 5 are coefficients.

What is Combining Like Terms?

Combining like terms is the grouping of similar terms to simplify algebraic equations consisting of several different variables and exponents. To understand the concept of combining like terms, you must understand the meaning of algebraic expressions.

So, algebraic expressions are algebraic equations. It is a relationship between variables, exponents, and coefficients in mathematical operations such as addition, subtraction, multiplication, and division. In an algebraic equation, variables can vary such as x, y, z, and so on. Meanwhile, the numbers used in algebraic equations are whole numbers, fractions, and decimals.

Below we give several examples of algebraic equations.

• c + 4fg + 12c + fg
• 3x + 4xy + 4x + 15xy
• 6c + 24y + 5c + y

From these examples, this will make it difficult for us to solve the equation so we need to use the concept of combining like terms to solve them.

To solve such equations using combining like terms, you must identify similar variables. For example in example 1: c + 4fg + 12c + fg. There are two variables in the equation; c and fg. If grouped, a new equation will be formed:

• c + 12c + 4fg + fg

Then, we can calculate them. Because the equation uses the addition operation, add similar variables.

• c + 12c = 13c
• 4fg + fg = 5fg

Well, the result is 13 c + 5fg. How? Very easy, right?

How to Teach Combining Like Terms to Students?

To teach combining like terms to students, do the following steps.

• First, explain about like terms. Give examples to help students understand your explanation and important terms related to like terms.
• Next, identify terms that are similar to like terms such as unlike terms.
• Then, start teaching students how to group like terms. Ask them to write like terms in the same section. This rearrangement helps students to be able to calculate like terms easily.
• After that, simplify the equation. Students can add colors or signs to the equation to simplify it easily. The use of shapes and colors becomes a visual aid for students. This also helps them to distinguish the +, -, x, or : signs in these calculation operations.
