Percentages, equations, geometry, algebra and more math tools.

Choose binomial or Poisson; compute P(X=k), E(X) and Var(X), with cumulative probability.

Enter f(x) and transform parameters to get the new g(x) expression and sample values, covering translation, scaling and reflection.

Simplify same-base multiplication/division, power of a power, negative and fractional exponents.

Change the subject from y to x (or vice versa) for y=ax+b, y=(ax+b)/(cx+d) and y=ax²+bx+c, with steps.

Direct, inverse, joint and partial variation: find k (and a) from conditions, then compute the unknown.

Compute a circle's radius, diameter, circumference and area from one known value.

Compute n! (factorial) and related values.

Compute the nth Fibonacci number and the ratio to the previous term.

Compute log_b(x) for any base, including natural and common logs.

Find the midpoint between two points in 2D or 3D.

Compute the slope, angle and line equation from two points.

Compute the distance between two points in 2D or 3D.
