Percentage, Algebra, Geometry, Fractions, Exponents, Logarithms, & Statistics. Access free, instant online tools with complete formula breakdowns, worked numerical examples, and verified calculation logic.

About Math & Science Calculators

The Math & Science category covers the full spectrum from everyday arithmetic to advanced geometry, statistics, and physics — all with step-by-step formula breakdowns that let you learn while you calculate. Every calculator shows the exact formula and each calculation step so you can verify and audit results independently.

The Percentage Calculator handles three modes: finding X% of Y, expressing X as a percentage of Y, and computing percentage change. For geometry, the Area Calculator covers 12 shapes including circles, triangles, and trapezoids, while the Pythagorean Theorem Calculator solves right triangles instantly. The Fraction Calculator handles all four operations with simplified results and decimal equivalents.

For data analysis, the Statistics suite (Mean, Median, Mode, Standard Deviation) provides complete descriptive statistics for any dataset. Whether you're a student double-checking homework, an engineer running quick estimates, or a professional needing a reliable reference, these tools deliver accurate results instantly.
