To add small numbers in Microsoft Word, you can use the superscript or subscript formatting options.

How to Add Small Numbers (Superscript or Subscript) in Word

• Superscript (smaller and raised numbers): Select the number or letter you want to make smaller and raised, then:
  • Go to the Home tab and click the Superscript button (it looks like "x²").
  • Or use the keyboard shortcut: Ctrl + Shift + + (plus sign).
• Subscript (smaller and lowered numbers): Select the number or letter you want to make smaller and lowered, then:
  • Go to the Home tab and click the Subscript button (it looks like "x₂").
  • Or use the keyboard shortcut: Ctrl + = (equal sign).

Where to Find These Options

• On the Home tab in the Font group, the superscript and subscript icons are available.
• You can toggle these formats on and off.
• These are commonly used for chemical formulas (e.g., H₂O) or exponents (e.g., 10²).

Additional Method - Symbol Dialog Box

• You can also insert superscript or subscript numbers via:
  • Insert tab > Symbol > More Symbols > select the "Superscripts and Subscripts" subset.
  • Choose the specific character to insert.

These methods make the numbers smaller and position them either above (superscript) or below (subscript) the normal text line for a clean look in your document.
