How to Use Nitrax Mathematical Keyboard with Windows Notepad

Open Notepad and type √(9) = 3 into a new note. Nitrax Mathematical Keyboard is a compact physical keyboard with mathematical, Greek and scientific symbols printed on its keys. After Windows setup, key combinations enter those symbols alongside ordinary text.

A short Notepad note lets you check whether a symbol enters correctly and whether its shape displays, before writing in another app. Keep the note as a .txt file for formulas, exercise instructions or working explanations.

Start with one square root

  1. Connect the keyboard and select its Windows mode with Fn + Q.
  2. Install and open the Nitrax Mathematical Keyboard app from Microsoft Store. Check that Math Mode is on, enabling the printed symbol combinations.
  3. Open Notepad, click inside your note and press Left Ctrl + Left Alt + T. You should see √ at the cursor.

For connection and installation details, follow the Windows quick-start guide.

Read the color, then type the symbol

Blue and gray are the two sets of symbols printed on the keys. Use the left-side Ctrl and Alt keys; add Shift for gray.

Gray integralLeft Ctrl + Left Alt + Shift + J∫

Release the modifiers to continue typing words and numbers. Right Ctrl and Right Alt are not substitutes for these Nitrax controls.

Square root: √(9) = 3
Integral notation: ∫ f(x) dx
Fraction written on one line: (a + b)/c

Type the words, numbers and punctuation normally; use the printed combinations when a symbol is needed. The keyboard enters characters. It does not calculate the answer or turn the integral into a formatted equation.

Save your note as a .txt file using UTF-8, a text encoding that preserves these characters, then reopen it to check the symbols. Microsoft documents Notepad’s UTF-8 saving support.

For stacked fractions, aligned equations or a root bar that stretches across an expression, use an equation editor. Here, √(9) remains a square-root character followed by ordinary text.

For technical text files, see typing math in Notepad++.

Use Notepad to check symbol input

Try the square-root combination before moving to a longer document. Compare the result with the expected √ above.
