Percentage

The four most common percentage calculations in a single tool.

Scientific

Trigonometry, logarithms, exponentials and factorials, with a degrees/radians switch.

Rule of three

Solve direct and inverse proportions by entering the three known values.

Average

Paste your list of numbers and get the mean, median, mode, range and standard deviation.

Fractions

Add, subtract, multiply or divide two fractions and get the result already simplified.

Quadratic equation

Solve ax² + bx + c = 0 with the discriminant, both roots and the parabola vertex.

Areas

Calculate the area and perimeter of squares, circles, triangles, trapezoids and ellipses.

Equations

Solve equations of the form ax + b = c and check the answer automatically.

Derivatives

Differentiate functions symbolically and evaluate the derivative at a given point.

Integrals

Compute the area under a curve between two limits using Simpson’s rule.

Powers

Raise any number to an integer, decimal or negative exponent.

Pythagoras

Find the hypotenuse or a leg of a right triangle, with area and perimeter.

Roots

Calculate roots of any index, including negative numbers with an odd index.

Logarithms

Compute the logarithm in any base and read ln, log₁₀ and log₂ at the same time.

Volume

Volume and surface area of cubes, spheres, cylinders, cones, prisms and pyramids.

GCD

Find the GCD of two or more whole numbers using Euclid’s algorithm.

LCM

Compute the LCM of several numbers to add fractions or synchronise repeating cycles.

Matrices

Add, subtract and multiply matrices, and compute determinants and transposes.

Mathematics

This section covers everything from everyday arithmetic to differential calculus. Every tool shows the formula it applies and a worked example, so you can verify the result by hand.
