Latex Equation Editor Calculator

LaTeX Equation Editor works out LaTeX and Calculator notation from Expression or LaTeX, Direction and Wrap the LaTeX for display. The default figures on this page give laTeX of \frac{a + b}{2}; change any entry and the result, the working and the sources update together.

LaTeX
\frac{a + b}{2}
LaTeX Equation Editor
Calculator notation
(a + b)/2
LaTeX with display delimiters
\(\frac{a + b}{2}\)
Conversion verified by round trip
yes
Worked out from LaTeX2e for authors, section on mathematical formulas (\frac, \sqrt, superscripts, log-like functions) and 1 other source.
No value was given for a, b, so the expression was converted but not evaluated.

Your figures

Updates as you type
Type ordinary calculator notation to get LaTeX, or paste LaTeX to get calculator notation. A backslash anywhere means it is read as LaTeX.
Give a value to each letter to evaluate the expression as well as convert it.

How this is worked out

2 steps
  1. Parsed (a + b)/2 into an expression tree.
  2. LaTeX: \frac{a + b}{2}
Variables foundtable
a, b

What the LaTeX Equation Editor calculates

Converts an ordinary calculator expression into LaTeX and LaTeX back into calculator notation, evaluates either, and verifies the conversion by comparing the two forms at sample points.

How to use this LaTeX Equation Editor

Enter Expression or LaTeX, Direction, Wrap the LaTeX for display and Values for the variables (optional). LaTeX updates as you type, and “Use a worked example” loads checked figures you can adjust. Change one figure at a time to see what drives the result.

How the result is worked out

Open “How this is worked out” beside the result for the step-by-step calculation behind LaTeX, Calculator notation and LaTeX with display delimiters.

The method follows LaTeX2e for authors, section on mathematical formulas (\frac, \sqrt, superscripts, log-like functions) and AMS, Short Math Guide for LaTeX (upright names for log-like functions, \cdot and \times for multiplication).

A quotient becomes a \frac example

With Expression or LaTeX: (a + b)/2, Direction: to-latex, Wrap the LaTeX for display: none, the calculator returns LaTeX: \frac{a + b}{2}, Variables found: see result table. This example is checked against an independent source in the test suite.

Results are general information, not financial, tax, legal, medical or engineering advice. Check any decision that matters with a qualified professional.

Frequently asked questions

How do I insert an equation editor?

Converts an ordinary calculator expression into LaTeX and LaTeX back into calculator notation, evaluates either, and verifies the conversion by comparing the two forms at sample points. Open “How this is worked out” beside the result to see each step for your own figures.

How do I code equations in LaTeX?

It needs Expression or LaTeX, Direction, Wrap the LaTeX for display and Values for the variables (optional). Nothing else is required, and the figures stay in your browser.

Can you provide me with an online LaTeX equation editor?

Converts an ordinary calculator expression into LaTeX and LaTeX back into calculator notation, evaluates either, and verifies the conversion by comparing the two forms at sample points. Put your own figures in above and the working updates beside the result. For scale, the default figures on this page give \frac{a + b}{2}.

Do mathematicians use LaTeX?

The result gives LaTeX, Calculator notation, LaTeX with display delimiters, Value, Variables found and Conversion verified by round trip, each labelled with its unit so the figure can be read on its own.

What information do I need for the LaTeX Equation Editor?

You need Expression or LaTeX, Direction, Wrap the LaTeX for display and Values for the variables (optional). The page opens with default figures that give laTeX of \frac{a + b}{2}, so you can see the scale before entering your own.

What does this LaTeX Equation Editor show?

It shows LaTeX, Calculator notation, LaTeX with display delimiters, Value, Variables found and Conversion verified by round trip, with the working and any warnings for your entries.
