Adding And Subtracting Like And Unlike Terms Addition and Subtraction of like terms can be done together Addition and Subtraction of unlike terms cannot be done together 13x 2 5x 2 is an example of like terms 7z 25r is an example of unlike terms
Addition and Subtraction of Like Terms We can simplify algebraic expressions or equations by combining the like terms for addition or subtraction Note that when we combine like terms we take their signs along with them To add like terms only focus on the coefficients Add the coefficients and keep the variable part as it is Unlike terms cannot be combined by adding or subtracting The terms whose variables and exponents are the same are known as like terms and the terms having different variables are unlike terms Let us understand this with an example

Collecting like terms is a way of simplifying algebraic expressions It is also known as combining like terms To do this we identify the like terms in an algebraic expression and combine them by adding or subtracting See also Simplifying expressions 3a Here s a step by step process of combining like terms involving adding or subtracting terms with the same variables and exponents Step 1 Identify Like Terms Begin by identifying the terms in the expression that have the same variables and exponents Like terms are 3x and 5x 2y and 7y
In this article you are going to learn the definition of like and unlike algebraic terms in Maths with more examples What are Like Terms In Algebra the like terms are defined as the terms that contain the same variable which is raised to the same power To simplify an algebraic expression that consists of both like and unlike terms we need to Step 1 move the like terms together Step 2 add or subtract their coefficients When moving the terms we must remember to move the or attached in front of them For example How to identify like terms and combine like terms

When we are dealing with quantities of the same type we may combine them using addition and subtraction An algebraic expression may be simplified by combining like terms This concept is illustrated in the following examples 8 records 5 records 13 records Eight and 5 of the same type give 13 of that type quot Like terms quot are terms whose variables and their exponents such as the 2 in x 2 are the same In other words terms that are quot like quot each other Note the coefficients the numbers you multiply by such as quot 5 quot in 5x can be different
