Fractions, algebra, statistics and exam-ready tools

These calculators show the working, not only the answer, which matters when you are checking a textbook result or an exam paper. Fractions, roots, exponents and quadratics follow the standard order of operations and the usual algebraic methods. The statistics calculator covers mean, median, mode, range, variance and standard deviation, while the scientific notation tool converts between standard and exponent form and works through addition, subtraction, multiplication and division in scientific notation. Significant figures applies the usual rounding conventions, and the GPA calculator supports the common weighting schemes so you can compare offers the way a university would.
