3. Choose 'Condensed' or 'Very condensed' to reduce the space between the lines. This will bring the letter and number closer together.

Applying This Technique in Different Scenarios

Now that you know how to make a number under a letter in Google Docs, let's explore some practical applications:

Mathematical Equations

You can use this technique to write mathematical equations like A², B³, or X₁Y₂. This can be particularly useful when writing physics equations, chemical formulas, or mathematical proofs.

For example, to write 'A squared', type 'A', make it superscript, then type '²' and make it subscript. This will give you 'A²'.

Chemical Formulas

In chemical formulas, you can use this technique to write subscripts for elements like H₂O (water) or CO₂ (carbon dioxide). To write 'H₂O', type 'H', make it superscript, then type '₂' and make it subscript. Repeat this for 'O'.

With this knowledge, you're now equipped to create numbers under letters in Google Docs for various purposes. Happy writing!
