Math Solver: Calculus, Algebra

Math Solver isn't just a number-crunching calculator — type in an actual math expression, and it gives you the answer along with a full step-by-step solution, all at once.
It never just drops an answer and moves on. Every result comes with a clear breakdown of exactly how it was reached.
From middle and high school homework to college-level calculus and linear algebra, to engineering and statistics — whenever you need to see how an answer was actually derived, you can check it instantly.

■ Basic Notation

- Exponents, roots (nth root), fractions, absolute value
- Trig function powers (sinⁿ, etc.), subscripts, degrees (°), percent (%)
- Complex numbers (i), approximate values (≈)

■ Special Functions

- Logarithms (base 2, 10, or n), natural exponential (eˣ), power functions (aˣ, xʸ)
- Factorial (n!), permutations (nPr), combinations (nCr)
- Floor and ceiling functions

■ Calculus

- Derivatives, partial derivatives, higher-order and mixed partial derivatives, chain rule
- Gradient, directional derivative, tangent plane
- Indefinite integrals, definite integrals, improper integrals, arc length, double integrals, line integrals
- Limits, multivariable limits
- Sigma (Σ) sums, Pi (Π) products
- Taylor expansion, implicit differentiation, extrema, linear approximation, Lagrange multipliers

■ Equations / Inequalities

- Solving equations, inequalities, systems of equations
- Automatically distinguishes between evaluating a defined function (e.g. f(3)) and solving an equation (e.g. f(x) = 4)
- Inverse function calls (f⁻¹)

■ Sets

- Union (∪), intersection (∩), difference (−), complement, subset (⊆), empty set (∅)
- Symmetric difference (△), Cartesian product (×), power set (𝒫), element check (∈)

■ Number Theory · Algebra

- Rounding, greatest common divisor (GCD), least common multiple (LCM)
- Factoring, expansion, primality testing, prime factorization, modulo (mod)

■ Vectors · Matrices

- Matrix arithmetic, reusable named matrices (A, B, ...), matrix power/inverse, determinant, transpose, trace, rank
- Eigenvalues, eigenvectors
- Vectors, dot product, cross product, matrix addition, matrix multiplication
- Tangent line of a surface intersection

■ Statistics

- Mean, standard deviation, variance, median, mode

■ Others

- Piecewise functions, atan2

■ And more

- Renders your input in real time with KaTeX, so you can see exactly what you typed
- Automatically saves your calculation history — revisit past problems and their solutions anytime
- Supports Korean and English (help content switches automatically based on your app language)

Who is this for?

- Students frustrated that regular calculator apps never explain how they got the answer
- Anyone who wants to double-check their work after solving homework or assignments
- Students reviewing or preparing for calculus, linear algebra, statistics, and other college courses
