## Unit checklist
Work through every section below, then take the final exam quiz.
Variables and Expressions
A variable represents an unknown value. An algebraic expression combines numbers, variables, and operations without an equals sign. Evaluate expressions by substituting values for variables. Exponents show repeated multiplication.
Combining Like Terms
Like terms have the same variable raised to the same power. Combine 3x + 5x to get 8x. Constants combine separately. Simplifying makes expressions easier to work with before solving equations.
The Distributive Property
a(b + c) = ab + ac. Distribute multiplication over addition or subtraction inside parentheses. Factoring is the reverse: pull out a common factor. Both skills appear throughout algebra.
Solving Equations
An equation states two expressions are equal. Solve by isolating the variable using inverse operations. Do the same operation to both sides. Check solutions by substituting back into the original equation.
FAQ
- Does this include two-step equations?
- Yes. Sample questions cover both one-step and two-step equations with integers.
- How does this prepare students for Algebra I?
- These skills form the foundation for linear equations, inequalities, and function notation in high school.
