Put algebra in motion.

Equation Visualizer lets you practise solving linear equations by dragging coloured numbers, variables, coefficients, and denominators. Explore rearrangement, distribution, combining like terms, splitting fractions, common denominators, and simplification with your hands. Every step is recorded so you can review the full solution. Ten built-in exercises progress in difficulty, and you can enter your own equation. Custom mode supports taking or selecting a photograph, cropping the problem, and recognising it on the device. Review and correct the result before loading it. Free, ad-free, and usable without registration or a network connection. Supports Traditional Chinese, Simplified Chinese, English, Japanese, and Korean.
