Mathematics & statistics calculators

The mathematics section covers the day-to-day calculations students, teachers and exam aspirants run into: a scientific calculator with trigonometry and logarithms, percentage and fraction tools, square / cube roots and powers, LCM and HCF, prime-number checks, quadratic equation solving, area of common shapes, statistics (mean, median, mode, standard deviation, variance), random number generation and base conversion.

These calculators use the standard arithmetic, algebraic and statistical formulas from school and college textbooks. Each tool shows the formula it uses so you can verify the steps by hand — useful for homework, competitive-exam preparation and quick checks during everyday work.

When to use these tools: Use these tools for homework, exam prep, quick computations during work, or anytime you need a fast answer without opening a spreadsheet.
