Algebra 1: Solving Inequalities Algebraically

General Skills

5 courses

Master the algebraic solution of linear inequalities. You will learn to interpret symbols, solve multi-step problems, and represent ranges on number lines and in interval notation. Apply these skills to real-world scenarios like budgeting, pricing comparisons, and threshold alerts.

You'll discover what inequality symbols really mean and how to compare quantities with confidence. You'll translate everyday phrases like "at least" and "no more than" into symbols, test whether a value fits a range, and learn to both draw and read inequalities on a number line.

Course 2

Solving One-Step Inequalities

5 lessons

21 practices

You'll start solving inequalities the same way you solve equations, using inverse operations to isolate the variable. You'll master the one rule that makes inequalities different — flipping the sign for negatives — handle the variable landing on either side, and confidently solve any one-step inequality in any form.

Course 3

Solving Multi-Step Inequalities

5 lessons

20 practices

You'll extend your one-step skills to inequalities that need several moves first. You'll combine like terms, expand parentheses, handle variables on both sides, and learn to read the unusual results that mean every number works or no number does.

Course 4

Representing and Interpreting Solutions

4 lessons

17 practices

You'll express inequality solutions in several connected ways. You'll write interval notation, move fluently between inequalities, number lines, and intervals, and interpret what a solution means in everyday situations.

Course 5

Solving Compound Inequalities

6 lessons

24 practices

You'll tackle inequalities built from two conditions joined by "and" or "or," and see how each connective shapes a different solution set. You'll solve both types, including three-part chained inequalities, and show your solutions on a number line and in interval notation.

It's an amazing product and exceeded my expectations, helping me prepare for my job interviews. Hands-on learning requires you to actually know what you are doing.

Alex Bush

Full Stack Engineer

I'm really impressed by the AI tutor Cosmo's feedback about my code. It's honestly kind of insane to me that it's so targeted and specific.

Abbey Helterbran

Tech consultant

I tried Leetcode but it was too disorganized. CodeSignal covers all the topics I'm interested in and is way more structured.
