New equation was inserted:

How to avoid this. What is the "special way" to reference equation in document text so it will be updated automatically when equation number change.

Answer 1

_{Uhm, you are referencing equation 1, so it's still 1 afterwards. Try referencing equation 2...}

Look for functionality to update the references if the above is by accident and the problem persists.

You can number equations in OpenOffice:

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

Answer 2

You could also make numbered equations in a special way though. For this You should type right in Your document fn and then press F3. A template for a numbered equation should appear.

What F3 calls is the autotext expansion. Here You call autotext which has a shortcut fn - it stands for "Formula Numbering".
