Key Concepts

Like Terms

Like terms are terms in an algebraic expression that have identical variables raised to the same power, making them eligible for arithmetic combination. Recognizing like terms allows you to simplify expressions by adding or subtracting their coefficients.

Combining Like Terms

Combining like terms involves adding or subtracting the coefficients of terms that have the same variable part, thereby reducing the complexity of an algebraic expression. This process is a fundamental technique in algebra used to simplify expressions and solve equations.

Algebraic Expressions

An algebraic expression is a mathematical phrase that can include numbers, variables, and arithmetic operations. Simplifying these expressions by combining like terms is an essential skill in algebra that aids in both evaluation and further manipulation in equations.

Coefficient

A coefficient is the numerical factor that multiplies the variable in a term. In the process of combining like terms, the coefficients are combined, which simplifies the overall expression while the variable part remains unchanged.
