LaTeX Calculator
Enter math in a 2D LaTeX-style field, calculate the result, and copy the expression as LaTeX for notes, homework, and documents.
LaTeX-style calculator for readable math expressions
This LaTeX calculator displays expressions in a math layout and lets you copy the input as LaTeX.
It is useful when you want a calculator that doubles as a quick formula editor for fractions, roots, powers, logs, and trig functions.
Features
- 2D math input powered by a math field instead of a plain textarea.
- LaTeX copy for the current expression.
- Fraction, root, power, log, trig, absolute value, and factorial templates.
- Safe numeric evaluation for supported real-number expressions.
- History for quickly reloading previous formulas.
Example expressions
\frac{a}{b}\sqrt{x^2+1}\frac{\log(100)}{\ln(e^2)}\sin(30^\circ)^2\left|\frac{-3}{4}\right|\sqrt[3]{8}
How to use this calculator
- Create the expression visually with the keyboard or template buttons.
- Copy the input as LaTeX when you need it for notes or documents.
- Replace variables with numeric values before calculating a result.
Common input mistakes
- This is not a symbolic algebra system; variables are displayed but not solved.
- Use supported functions such as sin, log, ln, sqrt, and abs when you want a numeric result.
- Keep function arguments grouped so the LaTeX and calculation expression match.
FAQ
Can I paste LaTeX into the calculator?
Many common LaTeX forms are recognized by the math field, and the buttons also create LaTeX-style structures.
Does the result copy as LaTeX?
The result is numeric, while the input expression can be copied as LaTeX.
Does it use eval?
No. Calculation uses a safe expression parser rather than JavaScript eval.
Can I use it only as a formula editor?
Yes. You can build a readable expression and copy the LaTeX even if the expression contains variables.
