Math Expression Calculator
Calculate math expressions with fractions, roots, powers, parentheses, logs, trigonometry, constants, and factorials in a 2D input field.
Math expression calculator with readable 2D input
Use this math expression calculator when a formula is too structured for a plain text input.
It separates the visual expression from the internal calculation expression, which makes complex input easier to read and check.
Features
- Arithmetic, parentheses, fractions, powers, roots, trig functions, logs, constants, factorials, and absolute values.
- 2D math field instead of a textarea.
- Implicit multiplication for common calculator-style input.
- Error handling for incomplete or unsupported expressions.
- Calculation history and copy controls.
Example expressions
\frac{1+\sqrt{5}}{2}\sqrt{1+2^2}(1+2)^3\log(100)+\ln(e)\left|\frac{-3}{4}\right|2\pi
How to use this calculator
- Build the expression with keyboard shortcuts or button templates.
- Check the displayed 2D math before calculating.
- Use the copied result or Ans for the next expression.
Common input mistakes
- Undefined symbols such as x cannot be evaluated until you replace them with numbers.
- Use balanced parentheses and complete fraction fields.
- Check whether adjacent values mean multiplication, such as 2pi or 2(3+4).
FAQ
What expressions are supported?
Arithmetic, parentheses, fractions, powers, roots, trig functions, logs, constants, factorials, and absolute values are supported.
Can it solve equations?
No. It evaluates numeric expressions and does not solve symbolic equations.
What happens if the expression is invalid?
The calculator shows a friendly error message instead of running unsafe code.
Can I use implicit multiplication?
Yes. Common forms such as 2pi, 2(3+4), and 2sin(30) are handled.
