1. Insert a Built-In Equation

Microsoft Word includes a library of ready-made equations for common mathematical expressions.

Steps:

1. Open your Word document.
2. Go to the Insert tab.
3. Click on Equation (π icon).
4. A dropdown will appear with pre-formatted equations, such as:
   • Quadratic formula
   • Binomial theorem
   • Area of a circle
5. Click on any equation to insert it into your document.

This is the easiest way to add common formulas without typing them manually.

2. Create Your Own Equation Using the Equation Editor

If you need a custom formula, you can type it using Word’s built-in equation editor.

Steps:

1. Go to the Insert tab.
2. Click Equation.
3. A new editable equation box will appear.
4. Use the Equation Tools – Design tab that appears at the top.
5. Choose from symbols and structures such as:
   • Fractions
   • Integrals
   • Summations
   • Operators
   • Scripts (subscripts and superscripts)
   • Radicals

Example:

Type your equation using math symbols, e.g.:

E = mc^2

Word automatically formats it as a professional mathematical expression.

3. Use Keyboard Shortcuts (Alt + =) for Quick Equations

A faster way to insert an equation box is:

Press:

Alt + =

This instantly inserts a math equation field so you can start typing right away.

4. Insert LaTeX-Style Equations

Word supports typing equations using LaTeX syntax.

Steps:

1. Insert an equation using Alt + =.
2. Type LaTeX-style input such as:
   • \frac{a}{b}
   • \sqrt{x}
   • \int_0^1 x^2 dx
3. Press Space, and Word will convert it to a formatted equation.

If your Word version supports it, you can also switch input mode:

• Go to File → Options → Proofing
• Click AutoCorrect Options
• Select the Math AutoCorrect tab
• Enable “Use Math AutoCorrect rules outside of math regions”

5. Insert Handwritten Equations (Ink Equation)

If you’re using a touchscreen or stylus, you can write equations by hand.

Steps:

1. Go to Insert → Equation.
2. Select Ink Equation.
3. Write your equation in the writing panel.
4. Word converts it into typed math.

This is especially useful for complex math that’s easier to write than type.

6. Insert Equations in Word Online

Word Online also supports equations but with limited features.

Steps:

1. Go to Insert → Equation.
2. Type your expression using the math toolbar.

While not as full-featured as the desktop version, it covers basic needs.

7. Formatting and Editing Equations

Once inserted, you can edit or format your equations:

• Click the equation to open Equation Tools – Design
• Change font size or style
• Align equations using paragraph tools
• Right-click for additional formatting options

You can also copy, paste, or move equations like any other text element.

Final Tips

• Use Math AutoCorrect to speed up typing.
• Use professional format for academic or technical documents.
• Save commonly used equations to your Equation Gallery for quick access.
• Use LaTeX input if you’re familiar with it—it’s much faster for advanced equations.
