MultiCal

Super Calculator is an all-in-one math and science toolkit: a powerful scientific calculator, graphing, advanced math solvers, a 23-category unit converter and a formula library for Math, Physics, Chemistry, Biology and Geography. Core tools work offline.

★ SCIENTIFIC CALCULATOR

- Full expression entry: brackets, powers, roots, factorial, percent, π, e and Ans

- sin, cos, tan, inverse and hyperbolic functions, log, ln, √, ∛

- Complex numbers, e.g. (3+2i)(1−i), with polar form

- DEG / RAD modes and live result preview while you type

- Exact forms: fractions and simplified radicals such as √2/2

- Memory keys (MC, MR, M+, M−, MS), history and saved formulas

- Copy results, dark and light themes, custom background colour

★ ADVANCED MATH

- Matrices: add, subtract, multiply, determinant, inverse, transpose, rank, trace, linear systems, eigenvalues and eigenvectors

- Polynomial equations with real and complex roots, numeric root finder

- Derivatives, definite integrals, limits, series, arithmetic and geometric sequences

- Combinatorics and probability, fractions and radicals

- Step-by-step evaluation that shows every operation in order

- LaTeX input

★ EQUATION SOLVER

- Linear equations, with the standard form and the solution

- Quadratic equations: discriminant, real or complex roots, Viète sum and product

- Polynomial equations up to degree 10, with multiple roots marked

- Systems of equations with several unknowns: unique solution, infinitely many solutions or no solution

- Numerical solutions with iterative methods: Newton–Raphson, bisection, secant, fixed-point and false position, with an iteration table

- Nonlinear equations: finds all real roots in an interval you choose

- Shows real roots, complex roots and the domain (conditions of existence), and rejects roots that violate it

★ GRAPHING

- Plot y = f(x) (up to 3 curves), parametric and polar curves

- Pinch to zoom, drag to pan, trace along the curve

- Find roots and extrema

★ PHYSICS & SCIENCE

- Physical constants and your own custom constants

- 2D/3D vectors: dot and cross product, angle, projection

- Significant figures and measurement error

- SI ⇄ CGS converter

★ UNIT CONVERTER
