Arithmetic, algebra, geometry, trigonometry, calculus, statistics, number theory. Every tool here shows step-by-step solutions — which honestly makes them as useful for learning the math as for checking an answer. I built them to be the kind of resource I wished I'd had in college.
The step-by-step breakdowns are the point, not an afterthought. You don't just get a number — you see the method. Students use these to verify homework. Professionals use them for quick sanity checks. And anyone who's ever stared at a formula thinking "wait, how does this work again?" will appreciate that the work is shown every time.
The calculations people actually need most often: percentage of a number, percentage change between two values, tip splitting, and proportions. Simple stuff, but easy to second-guess.
Quadratic equations, logarithms, and standard algebraic operations — with step-by-step breakdowns so you can follow the work, not just copy the answer.
Areas, volumes, surface areas, and dimensions for circles, triangles, rectangles, and irregular shapes. Handy for everything from homework to figuring out how much paint you need.
Averages, standard deviation, confidence intervals, probability, and sample size calculations. Covers the stats you'd actually encounter in a class or a report.
Fraction simplification, mixed number conversions, GCF, LCM, and decimal operations. The kind of math that should be simple but somehow never is when you're doing it in your head.
