Word’s equation editor is built in, so you don’t need an add-in for school or research formulas. Every method below creates a real, editable Word equation that stays sharp in print and PDF.
- Insert an equation box
- Hand-write an equation with Ink Equation
- Build an equation with the Equation tab
- Type equations with linear shortcuts
- Insert a built-in equation
- Bring in equations from ChatGPT or LaTeX
Inserting an equation box
Use this when you know what you want to type and just need a place to type it.
- Click where the equation should go.
- Press Alt + = on Windows. On any platform you can also go to Insert > Equation (on Windows, Insert > Equation > Insert New Equation).
- Type your formula inside the box that appears.
Result: Word adds a “Type equation here” box and opens the Equation tab on the ribbon.
Hand-writing an equation with Ink Equation
Use this when a formula is faster to draw than to type, especially on a touch screen or with a pen.
- Press Alt + = to open the Equation tab.
- Select Ink Equation. Microsoft also lists it under Draw > Ink to Math.
- Write the equation in the yellow area with your mouse, pen or finger.
- Use Erase or Select and Correct to fix any part Word misreads. Check the preview at the top.
- Select Insert.
Result: your handwriting becomes a typed equation in the document.
Tip: Write large and leave space between terms. Recognition improves noticeably when superscripts are clearly raised.
Building an equation with the Equation tab
Use this when the formula has fractions, radicals, integrals or matrices and you want to build it piece by piece.
- Open an equation box with Alt + = or Insert > Equation.
- On the Equation tab, open a gallery in the Structures group, such as Fraction, Script, Radical, Integral or Bracket.
- Pick a layout. Word inserts it with small dotted placeholder boxes.
- Click each placeholder and type its value. Placeholders can hold further structures, so you can nest a radical inside a fraction.
- Add Greek letters and operators from the Symbols group. Select the More arrow to see every symbol set.
Result: a fully structured equation that you can edit later by clicking it.
The second video below builds a complex equation from scratch with these tools, including fractions, superscripts and integrals.
If you only need a single character, such as π or ±, see our list of special symbols in Word instead.
Typing equations with linear format shortcuts
Use this when you want speed. Linear format lets you type math on one line and Word builds it up for you.
- Open an equation box with Alt + =.
- Type the formula in linear form, for example:
a/bthen Space for a fraction;x^2then Space for a superscript, andx_1for a subscript;\sqrt(x)then Space for a square root;\alpha,\pior\sumthen Space for symbols;\degreefor a degree sign, and\Deltaor\deltafor the delta symbol.
- To convert the whole equation at once, select Convert > Professional, or press Ctrl + = on Windows.
- To see the source text again, choose Linear from Convert, or press Ctrl + Shift + =.
Result: the typed text becomes a properly formatted equation.
These codes are Word’s Math AutoCorrect entries. Microsoft’s guide to UnicodeMath and LaTeX linear format lists them all, and they are case-sensitive.
Inserting a built-in equation
Use this when you need a standard formula, such as the quadratic formula or the Pythagorean theorem.
- Click where the formula should go.
- Go to Insert and select the arrow next to Equation.
- Pick a formula from the gallery.
- Edit the values if needed.
Result: the ready-made formula appears in your document.
Tip: To reuse your own formula, select it, open the equation’s drop-down arrow and choose Save as New Equation. It then appears in the same gallery.
Bringing in equations from ChatGPT or LaTeX
Use this when the equations already exist somewhere else, in an AI answer or in LaTeX source.
- LaTeX code: in Word for Microsoft 365, set the equation’s input to LaTeX on the Equation tab, then paste the formula. Our guide to pasting a LaTeX equation into Word shows each step, and the same article covers converting a whole .tex file.
- ChatGPT answers: copying a ChatGPT answer often pastes the maths as plain text. Our ChatGPT to Word or PDF extension exports a response, including its equations, as a Word file. For every method, including Gemini, see how to copy math equations from ChatGPT or Gemini to Word.
- Claude: with Anthropic’s add-in you can use Claude in Microsoft Word to draft and edit inside the document.
Check AI-generated maths before you rely on it. The formatting may be right while the formula itself is wrong.
Comparing the methods
| Method | Best for | Works on |
|---|---|---|
| Equation box (Alt + =) | Any new equation | Windows (shortcut); Mac and web via Insert |
| Ink Equation | Handwritten formulas, touch screens | Word for Windows |
| Equation tab structures | Complex, nested formulas | Windows, Mac |
| Linear format shortcuts | Fast typing once you know the codes | Windows, Mac |
| Built-in equations | Standard textbook formulas | Windows, Mac |
| LaTeX input or AI export | Formulas that already exist elsewhere | Word for Microsoft 365 (LaTeX input) |
Platform differences
- Windows: every method works. Alt + =, Ctrl + = and Ink Equation are Windows features.
- Mac: go to Insert > Equation, then use the Equation tab’s structures, symbols and linear typing. Ink Equation isn’t available.
- Word for the web: current versions can insert and edit equations from Insert > Equation, but the tool set is smaller. Use Open in Desktop App for Ink Equation or LaTeX input.
- Google Docs: it has its own, simpler editor; see how to write math equations in Google Docs.
Troubleshooting equations in Word
- Equation is greyed out: the file is probably an old .doc in Compatibility Mode. Save it as .docx with File > Save As.
- \alpha stays as text: you typed it outside an equation box. Press Alt + = first, or turn on Use Math AutoCorrect rules outside of math regions under File > Options > Proofing > AutoCorrect Options > Math AutoCorrect.
- An old equation can’t be edited: it was probably made with the legacy Equation Editor 3.0, which Microsoft has removed. Retype it with the current tools.
- Equations look wrong in a PDF: export with File > Save As > PDF rather than printing to PDF. See how to convert Word to PDF.
