Math Calculators

From homework to statistics, with the steps shown. Add and divide fractions with automatically simplified answers, get every average of a data set at once, compute both flavors of standard deviation, work out your GPA or the score you need on a final, and draw genuinely random numbers. Each page teaches the method alongside the answer.

  • Average Calculator

    Paste a list of numbers and instantly get the mean, median, mode, range, sum, min, and max.

  • Standard Deviation Calculator

    Compute sample and population standard deviation, variance, and mean from any list of numbers — with the formulas and when to use each version.

  • GPA Calculator

    Calculate your GPA on the 4.0 scale: add courses with credits and letter grades (A to F, with plus/minus) and get your exact grade point average.

  • Grade Calculator

    Work out your weighted course grade from assignments and exams, or calculate exactly what score you need on the final to hit your target grade.

  • Random Number Generator

    Generate truly random numbers in any range — one or many, with or without duplicates, sorted or shuffled.
