Symbolab

Broad coverage across algebra, trigonometry, calculus, linear algebra and geometry with consistent step formatting, at the cheapest annual price of any full-step solver here. The practice generator produces variants with solutions, which is directly useful for differentiated worksheets.

Generating a tiered practice set — routine, twist, interpretation — with worked solutions for a flipped-classroom warm-up. Having students ask the chat why a step is valid and submit the exchange as a metacognition artifact, graded on the quality of their question. Building a self-check answer bank for an open lab so tutors spend time on reasoning.

Same assessment problem as Photomath but with wider reach — it handles multivariable calculus and linear algebra, so the affected course range is larger. It is a symbolic solver with an LLM wrapper, and the wrapper will narrate a confident but pedagogically wrong justification for a correct step. Recent free-tier tightening means students who relied on it free now hit a paywall mid-term, creating an equity gap in who has step access.
