## Description

[MathSolver] isn&#39;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.<br>It doesn&#39;t just hand you an answer and stop there. It breaks down exactly how that answer was reached, step by step.<br>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.<br><br>■ Basic Notation<br>- Exponents, roots (nth root), fractions, absolute value<br>- Trig function powers (sinⁿ, etc.), subscripts, degrees (°), percent (%)<br>- Complex numbers (i), approximate values (≈)<br><br>■ Special Functions<br>- Logarithms (base 2 · 10 · n), natural exponential (eˣ), power functions (aˣ, xʸ)<br>- Factorial (n!), permutations (nPr) · combinations (nCr)<br>- Floor · ceiling functions<br><br>■ Calculus<br>- Derivatives, partial derivatives, higher-order derivatives · mixed partials, chain rule<br>- Gradient, directional derivative, tangent plane<br>- Indefinite integrals, definite integrals, improper integrals, arc length, double integrals, line integrals<br>- Limits, multivariable limits<br>- Sigma (Σ) sums, Pi (Π) products<br>- Taylor expansion, implicit differentiation, extrema, linear approximation, Lagrange multipliers<br><br>■ Equations / Inequalities<br>- Solving equations, inequalities, systems of equations<br>- Automatically distinguishes between evaluating a defined function (e.g. f(3)) and solving an equation (e.g. f(x) = 4)<br>- Inverse function calls (f⁻¹)<br><br>■ Sets<br>- Union (∪), intersection (∩), difference (−), complement, subset (⊆), empty set (∅)<br>- Symmetric difference (△), Cartesian product (×), power set (𝒫), element check (∈)<br><br>■ Number Theory · Algebra<br>- Rounding, greatest common divisor (GCD), least common multiple (LCM)<br>- Factoring, expansion, primality testing, prime factorization, modulo (mod)<br><br>■ Vectors · Matrices<br>- Matrix arithmetic, named matrix definitions, matrix power · inverse, determinant, transpose, trace, rank<br>- Eigenvalues, eigenvectors<br>- Vectors, dot product, cross product, matrix addition, matrix multiplication<br>- Surface intersection tangent line<br><br>■ Statistics<br>- Mean, standard deviation, variance, median, mode<br><br>■ Others<br>- Piecewise functions, atan2<br><br>■ And more<br>- Renders your input in real time with KaTeX, so you can see exactly what you typed<br>- Shows not just the final answer, but every step of the solution along the way<br>- Supports Korean and English (help content switches automatically based on your app language)<br><br>Who is this for?<br>- Students who found regular calculator apps frustrating because they never explain how the answer was reached<br>- Anyone who wants to double-check their work after solving homework or assignments<br>- Students reviewing or preparing for calculus, linear algebra, statistics, and other college courses
