Learn Algebra. Actually Understand It. Cosuki is an algebra learning app built around one simple idea: understanding comes before memorization. Learn the concept. Follow a worked example. Practice it yourself. Then prove you’ve mastered it. From variables and expressions to the Grand Trial, Cosuki takes you through 10 carefully structured chapters covering inequalities, coordinate geometry, systems of equations, exponents, polynomials, quadratics, functions, and more. LEARN WITH PURPOSE Every chapter starts with clear concept guides that explain the rule, demonstrate a worked problem, and walk you through the reasoning behind every step. Then it’s your turn. Complete practice missions, build confidence, and finish with mastery tests designed to make sure the concept actually stuck. Each chapter includes 22 missions and 110 questions. When you make a mistake, Cosuki doesn’t just mark it wrong. It explains what happened and helps you understand the solution. When you’re stuck, hints help you move forward without simply giving away the answer. EARN YOUR PROGRESS Learning is the journey. The treasures are the proof.
