Scientific calculator
Type a whole expression and see the answer as you write it, or use the keypad. Degrees and radians both supported, with every result kept in a history list you can click to reuse.
How to use the scientific calculator
- Type an expression such as 12*(3+4)^2, or tap it out on the keypad.
- Switch between degrees and radians for trigonometry.
- Press Enter to save a result to the history, then click any entry to reuse it.
How it works
Expressions are parsed properly rather than evaluated left to right, so operator precedence works the way mathematics expects: multiplication before addition, exponents before multiplication, and brackets before everything. Implicit multiplication is understood too, so 2(3+4) and 2*(3+4) both give 14.
Available functions are sin, cos, tan and their inverses, sinh, cosh, tanh, log for base ten, ln for natural log, sqrt, cbrt, abs, exp, round, floor and ceil, plus the constants pi and e. The exclamation mark gives a factorial and the caret raises to a power.
Common questions
How do I calculate a square root?
Type sqrt(16), tap the √ key, or use a fractional power: 16^0.5.
What is the difference between log and ln?
log is base ten and ln is base e, roughly 2.718. Both are on the keypad.
Does it work in degrees?
Yes, and degrees is the default. Switch to radians with the toggle under the keypad if you are working in calculus.
