About this app

[MathSolver] isn't a calculator where you just punch in numbers. You type in the actual math expression, and it shows you the answer AND the step-by-step solution, all at once.
It doesn't just hand you an answer and stop there. It breaks down exactly how that answer was reached, step by step.
From middle and high school homework to college calculus and linear algebra assignments, to engineering and statistics — whenever you want to know 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 · n), natural exponential (eˣ), power functions (aˣ, xʸ)
- Factorial (n!), permutations (nPr) · combinations (nCr)
- Floor · ceiling functions

■ Calculus
- Derivatives, partial derivatives, higher-order derivatives · mixed partials, 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, named matrix definitions, matrix power · inverse, determinant, transpose, trace, rank
- Eigenvalues, eigenvectors
- Vectors, dot product, cross product, matrix addition, matrix multiplication
- Surface intersection tangent line

■ 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
- Shows not just the final answer, but every step of the solution along the way
- Supports Korean and English (help content switches automatically based on your app language)

Who is this for?
- Students who found regular calculator apps frustrating because they never explain how the answer was reached
- 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

What’s new

[수식계산기]는 숫자만 입력하는 계산기가 아니라, 수식 그 자체를 입력해서 정답과 풀이 과정을 한 번에 확인하는 수학 계산 앱입니다.
정답 하나만 던져주고 끝나지 않습니다. 그 정답이 어떻게 나왔는지, 어떤 단계를 거쳤는지 하나하나 풀어서 보여드립니다.
중·고등학교 수학 숙제부터 대학 미적분·선형대수 과제, 공학·통계 계산까지 — 정답이 어떻게 나왔는지 궁금할 때 바로 확인할 수 있습니다.
