Operate
Maths.
Compute, visualise, differentiate and look things up in one calm workspace. Every tool runs instantly in your browser — no accounts, no waiting, no hidden steps.
Five instruments.
One system.
Each tool is a real mathematics engine — a hand-written parser, not a decorative mockup.
Equation Solver
Linear, quadratic, cubic, 2×2 systems and numerical roots for any supported expression — with full working.
Function Grapher
Plot several functions at once with pan, zoom, trace, roots and an interactive coordinate readout.
Calculus Lab
Symbolic derivatives, definite integrals, limits, tangents, normals and critical points.
OMI
Ask any maths question and get a detailed step-by-step solution, with the formula named in brackets at every step.
ARIQ
Timed arithmetic practice with custom ranges, advanced question types, live streaks and a full score breakdown.
A place for the
things you forget.
Identities, formulas, laws of powers, square and cube roots, trigonometry, exponentials and logarithms — organised by topic, not by class.
