## Mixed reference

A mixed reference is a reference that is fixed only on part of the reference:

- either the row
- or the column

Before showing you an example of a calculation using mixed references, we will detail the use of the $ symbol in a reference.

**An absolute reference**** has two $**. There is one for the rows and one for the columns.

**But which one does what?** 🤔🤨🙄

In fact it's very simple, **just look the position of the $**

- If the $ is on the left of the letter it means you lock the column
- If the $ is on the left of the row number it means you lock the row

Press the key stroke

F4 multiple timesto change the position of the $.

## Multiplication table

To illustrate the use of a mixed reference, we will construct a multiplication table.

The idea here is to create a single formula and copy it for the rest of the document. This will save us writing the 99 other formulas 😉😉

We want to stay always on the headers of our table so we will write the formula as follows

=$B4*C$3

- Start by copying cell C4 (Ctrl + C)
- Then select all other cells
- Finally, paste the formula (Ctrl + V)

The multiplication table is now correct for every single cell.

We have created only one formula and copied it for the 99 other cells. How productive 👍😍😎

## Tips to know where to insert the $?

If creating a formula with mixed references is difficult for you at the first glance, use this trick to know where to put the $. 💡

- Repeat the previous year and this time write 3 or 4 formulas without any $.
- Your document looks like this

- Now, display the formulas of your document by activating the menu
**Formulas>Show Formulas**

- Your spreadsheet now looks like this

**Now look carefully at the formulas**. 🧐🧐🧐

You notice that for all formulas you have:

- always
**the column B** - and also always
**the row 3**

So it is easy to know where to put the $. It's before the column B and before the row 3 as these are the elements that never change.

## Mixed references in a Table

Finally, if you want to create a mixed reference in a Table (Insertion>Table), **YOU CAN'T**! ⛔⛔⛔

In a Table you can only create absolute or relative references
