Add like terms
for 6th grade
Simplify expressions by adding algebraic like terms such as a + a or b² + 3b² or 5c³ + 3c³
Adding like terms
When we talk about "like terms" in algebra, we are referring to terms that have the same variable(s) raised to the same power(s).
For example, 3x and 5x are like terms because they both have the same variable x raised to the same first power. Similarly, 2y² and 7y² are like terms because they both have the variable y raised to the second power. We have a topic about like and unlike terms.
To add like terms, you simply add the coefficients (the numbers in front of the variables) while keeping the variable and its exponent the same.
For example, to add 3x and 5x, you would add the coefficients 3 and 5 to get 8, and then write the result including the variable.
3x + 4x = 8x
Similarly, to add 3a³ and 4a³, you would add the coefficients 3 and 4 to get 7, and then write the result including the variable and the exponent.
3a³ + 4a³ = 7a³
