Math Calculators
Arithmetic, algebra, geometry, statistics, probability and number theory.
Percentages, averages, standard deviation, fractions, algebra and the other calculations that come up in coursework and in work. The pages show each step rather than only the answer, which makes them useful for checking homework or a spreadsheet as well as for getting a number quickly.
Where a calculation has more than one convention — sample versus population standard deviation, or percentage change against which base — the page says which one it uses and why, because that choice is usually where a hand calculation and a tool disagree.
