Frequently asked questions

Does it follow BODMAS?

Yes. Brackets come first, then powers, then × and ÷, then + and −. For example, 2+3×4 = 14.

What is the difference between DEG and RAD?

They are two units for angles. School problems usually use degrees (DEG), where sin(30) = 0.5. Radians (RAD) are used in higher maths, where sin(π/6) = 0.5.

Can I use my keyboard?

Yes. Type numbers and + − * / ^ ( ) ! %, press Enter for the answer, Backspace to delete and Escape to clear.

What's the difference between log and ln?

log is the logarithm to base 10 (log 100 = 2). ln is the natural logarithm to base e (ln e = 1).

How does % work here?

% divides the number before it by 100, so 50% = 0.5 and 200×15% = 30. For discounts and increases, our Percentage Calculator is easier.
