📐About Math & Science Calculators
Whether you're a student checking your homework, a teacher preparing examples, an engineer verifying a quick calculation, or a business analyst working with percentages — these math tools are built to handle everything from the trivially simple to the genuinely complex.
Start with the Percentage Calculator if you need to find X% of a number, calculate what percentage one number is of another, or work out a percentage increase or decrease — it solves all six common percentage problems simultaneously. The Scientific Calculator handles full mathematical expressions including trigonometry, logarithms, and exponent operations with a running history of your calculations.
What makes these implementations stand out: the Percentage Calculator shows all six calculation modes at once rather than forcing you to select a mode first. The Statistics Calculator produces a complete analysis — mean, median, mode, standard deviation, IQR, and quartile distribution — from a pasted list of numbers in under a second. Every algebraic calculator shows the step-by-step working, not just the final answer — which makes them genuinely useful for students learning the underlying method.
