Evaluate arithmetic and scientific expressions with brackets, powers, roots, logs and trigonometric functions.
How math is worked out
A general-purpose expression evaluator handles the cases a four-function calculator cannot: nested brackets, exponents, logarithms and trigonometry in one line, with correct order of operations throughout.
For specific tasks — fractions, percentages, statistics, geometry — the dedicated calculators on this site give more structured output than a plain expression result.
How to use it
- Type your expression.
- Use brackets to control the order of operations.
- Read the result.
The maths behind it
order of operations: brackets, exponents, multiplication and division, then addition and subtraction
Try it with these numbers
On the values this calculator opens with, the result is 12. Alongside it, Mode comes out at Radians. Change any field and every figure updates as you type.
Common questions
What functions are available?
Trigonometric, inverse trigonometric, logarithmic, exponential and root functions, plus the constants pi and e.
Does it follow order of operations?
Yes — unlike a basic pocket calculator, it applies full algebraic precedence.
