Sometimes you might need to** insert a math equation** **in PowerPoint** document, and fortunately Microsoft Office has this capability. If the built-in equations don’t meet the actual needs, you could edit or modify them or enter your own equation by handwriting, especially those with complex symbols and structures. Here I’d like to share 2 tips and let’s have a look:

**Tip 1: Insert Equation Directly**

1. Go to ** Insert** tab and click

**in**

*Equation***group.**

*Symbols*2. There are multiple equations in the drop-down list, just single-click what you want.

3. The equation you selected will be displayed automatically in the current slide.

4. Then ** Drawing Tools** and

**will appear, click**

*Equation Tools***and you can edit and modify the symbols or structures in the formula through tools in**

*Design***group.**

*Structures***Tip 2: Manual Input Formula**

1. Go to ** Insert** tab and click

**in**

*Equation***group.**

*Symbols*2. Click ** Ink Equation** at bottom of the drop-down list.

3. The handwriting board will display, simply drag the mouse to enter your formula. Note: If input error occurs, click the ** Erase** button and select the error part to clear it; if identification error occurs, click

**button, then select the symbol which need to be modified, and pick the correct one in the pop-up list to replace it. If you want to reenter the formula, click**

*Select and Correct***button then everything in the handwriting board will be deleted.**

*Clear*4. Make sure all the symbols or structures are correct, hit the ** Insert** at bottom right. The formula will be shown in the current slide.
