🔢 Math Calculators
Solve math problems instantly -- percentages, fractions, statistics, algebra, geometry, and more.
47 free calculators
From quick everyday arithmetic to university-level algebra and statistics, our math calculator collection has you covered. Every tool delivers instant, accurate results with step-by-step explanations -- making maths accessible whether you're a student, a teacher, or someone who just needs the answer fast.
Arithmetic and Number Theory
The most-used tools in our toolkit are the workhorses of everyday maths. The Percentage Calculator answers all three common percentage questions in one place. The Fraction Calculator handles addition, subtraction, multiplication, and division of fractions -- including mixed numbers -- and shows results in their simplest form. Need to work with very large or very small numbers? The Scientific Notation Calculator converts between standard and scientific format instantly.
For number theory, the LCM Calculator and GCF Calculator find the least common multiple and greatest common factor of any set of numbers. The Prime Factorization Calculator breaks any integer into its prime components, while the Prime Number Checker instantly tests whether a number is prime.
Algebra and Equations
Our Quadratic Formula Calculator solves any equation of the form ax^2 + bx + c = 0 with full discriminant analysis. The Slope Calculator and Midpoint Calculator handle coordinate geometry problems, while the Distance Formula Calculator computes the straight-line distance between two points. Linear algebra students can use the Matrix Calculator for determinants, inverses, and multiplication.
Geometry and Statistics
A full suite of geometry tools covers common 2D shapes (Area Calculator, Circle Calculator, Triangle Calculator) and 3D volumes (Sphere, Cylinder, Cone). For data analysis, the Standard Deviation Calculator and Mean Median Mode Calculator summarise any data set with a single input. The Probability Calculator computes simple and compound event probabilities.
