List of Commonly Used Math AutoCorrect Entries in Word 365

How to Use This Listing

This reference organizes Math AutoCorrect entries by mathematical category to help you quickly find the codes you need. Each section contains commonly used symbols within that area of mathematics. The examples show basic usage patterns that you can adapt for your needs.

Notes:

• Important: The AutoCorrect codes are case-sensitive.
• When spaces are important in the UnicodeMath examples provided below, a space is represented by the characters <sp>.
• In UnicodeMath, you can negate most mathematical relations by prefixing them with a forward slash (/). For example, typing /= produces ≠ (not equal), and /\subset produces ⊄ (not a subset). This convention provides a consistent, intuitive way to create negated relations that is easier to use than remembering separate AutoCorrect entries for each negated symbol.
• You can find these Math AutoCorrect codes directly in Microsoft Word:
  1. Open the Equation Toolbar
  2. Expand the Conversions menu
  3. View Equations Options
  4. Select the "Math AutoCorrect" tab.
• See Reference List Math Autocorrect Entries in MS Word 365 (Alphabetical) for a complete list of the Math AutoCorrect entries found in Microsoft Word 365 (sorted alphabetically by keyword).
• If no Math AutoCorrect entry exists for a common symbol listed below, we have provided the hexadecimal value for the symbol. Windows users can type the hexadecimal value and then press <Alt+x> to produce the symbol.
• For information on inserting a symbol that does not have a Math AutoCorrect entry, see Insert a symbol.
