Hi there!

I'd be happy to help you understand what the & symbol does in a formula.

In Excel, the & symbol is used to concatenate, or join together, two or more pieces of text. For example, if you have the text "Hello" in cell A1 and the text "world" in cell A2, you could use the formula to combine them into the phrase "Hello world".

Here's a step-by-step breakdown of how to use the & symbol in a formula:

1. Start by typing an equals sign (
   Code:

   =

   ) to begin your formula.
2. Type the cell reference or text string that you want to include first.
3. Type the & symbol.
4. Type the cell reference or text string that you want to include next.
5. Repeat steps 3 and 4 as many times as needed to concatenate all of the text strings you want to join together.
6. Close the formula with a closing parenthesis if necessary.

I hope that helps!
