Math Keyboard Comparator: Choose by What You Write

One sentence can send you looking for three symbols. Our pick for repeated symbol entry beside ordinary words is Nitrax Mathematical Keyboard. Other methods suit equation layout, graphing, touchscreen input or document typesetting.

Nitrax Mathematical Keyboard is a compact physical computer keyboard with letters and mathematical, Greek and scientific symbols printed on its keys. After setup, key combinations type symbols from its blue and gray printed layers. The symbol you choose appears in your document as a character.

Which part of writing math needs help?

Illustrative note

The angle θ must satisfy 0° ≤ θ ≤ 90°.

Here, θ names the angle, and ≤ marks its bounds. The task is entering symbols among ordinary words. Printed symbol keys give you a visible reference at your hands.

A stacked fraction or a matrix creates a different task: arranging several characters into a mathematical structure.

[\begin{matrix} a & b \\ c & d \end{matrix}]

Choose physical keys for the symbols you keep reaching for

If mathematical characters interrupt your writing repeatedly, Nitrax Mathematical Keyboard gives those characters a place on your keyboard. You can look at the printed symbol rather than keep a separate collection to copy from.

Keep your equation editor for stacked fractions, matrices and other structured notation. Nitrax Mathematical Keyboard enters symbols; it does not calculate, automatically lay out complete equations or replace LaTeX. App support and rendering vary, so check setup and compatibility for your computer and writing apps.
