Cymath

Cymath is a free math problem-solving app and website that returns detailed, ordered step-by-step solutions for algebra, calculus, trigonometry, and graphing problems, which students can enter by typing or by photographing the problem with their phone. It's built for K-12 and college students who want to check answers, understand their mistakes, and get extra homework help rather than just a final number. Its paid Cymath Plus tier differentiates it by explaining not only how each step is done but why it is taken across a wide range of topics.
