How it works

Type any expression into the display or tap it out on the keypad, then press =. The calculator parses your input with a proper grammar, so it respects the standard order of operations and lets you nest parentheses and functions freely.

Order of operations (PEMDAS)

1. Parentheses ( )
2. Exponents ^ and roots
3. Multiplication × and division ÷
4. Addition + and subtraction −

Worked example

The expression 3 × sin(30) + √(16) in degree mode evaluates like this:

StepValue
sin(30°)0.5
3 × 0.51.5
√164
1.5 + 45.5

Supported functions

Frequently asked questions

How do I switch between degrees and radians?

Use the DEG / RAD toggle above the keypad. In degree mode, trig functions treat input as degrees; in radian mode, as radians. Inverse functions return their result in the same unit.

What functions are supported?

Sin, cos, tan and inverses, ln and log, square root, exponents, factorial, percent, absolute value, exp, and the constants π and e, plus the usual operators and parentheses.

Does order of operations apply?

Yes — parentheses, then exponents, then × and ÷, then + and −, left to right.
