Scientific calculators
Full-function scientific keypad for advanced work.
The calculators here handle the math a basic arithmetic tool can't: trigonometric and logarithmic functions, matrix operations, statistical measures across a data set, and solving quadratic equations for their roots.
If what you actually need is a percentage, an average, or a fraction, the Basic Math calculators are simpler and faster for those — this category is for calculations that need more than the four basic operations.

Frequently asked questions
The Scientific Calculator lets you switch between degrees and radians directly — check which one your textbook or problem expects before reading the result, since the same input gives a different answer in each mode.
Yes — it's built for a list of values, returning mean, median, mode, standard deviation and variance for the whole set at once.
