Our math calculators cover everything from basic arithmetic to advanced algebra and statistics. Whether you're a student working through homework, a teacher preparing lesson materials, or a professional crunching numbers, our tools provide accurate results with clear explanations. Each calculator is built to handle real-world math problems — not just textbook examples — so you can use them for practical tasks like calculating discounts, analyzing data sets, or solving engineering equations.

For everyday math, our percentage calculator handles all common scenarios: finding what percent one number is of another, calculating percentage increase or decrease, and applying discounts or tax. The fraction calculator supports addition, subtraction, multiplication, and division of fractions with step-by-step solutions that show you exactly how to simplify results. These tools are especially valuable for students learning foundational math concepts.

For advanced work, our scientific calculator supports trigonometric functions, logarithms, exponents, and constants like pi and Euler's number. The standard deviation calculator and probability tools are essential for statistics coursework and data analysis. Whether you need to solve a quadratic equation, calculate the slope between two points, or find the circumference of a circle, each tool uses precise mathematical formulas and delivers results instantly.

All calculators run in your browser with no installation or signup required. They work on desktop, tablet, and mobile devices, making them accessible whenever you need a quick calculation or a detailed mathematical solution.

Looking for deeper statistical analysis? Our dedicated Statistics Calculators section covers mean, median, mode, variance, z-score, percentile, and more — each with worked examples, formula breakdowns, and guide pages to help you understand the math behind the numbers.
