Numbering Equations

Equation numbering is one of Math's best hidden features. The steps are simple, but obscure:

1. Start a new line in the Writer document.
2. Type fn and then press  F3 .

The fn is replaced by a numbered formula:

Now you can double-click on the formula to edit it. For example, here is the Riemann Zeta function:

You can reference an equation (“as shown in Equation (1)”) with these steps:

1. Choose Insert → Cross-reference from the menu bar.
2. On the Cross-references tab (Figure 218), under Type, select Text.
3. Under Selection, select the equation number.
4. Under Format, select Reference.
5. Click  Insert .

Done! If you later add more equations to the paper before the referenced equation, all the equations will automatically renumber and the cross-references will update.

To insert the equation number without parenthesis around it, choose Numbering instead of Reference under Format.
