# Adding number to formula automaticly

Hi,

As I can see in LibreOffice Math guide (p29, https://wiki.documentfoundation.org/i...) the equations are numbered like this:
`(#) [some equation] or (1) y=ax+b `

How can I create an automatic formatting like this? My LO is v5.3.7.2.0 (Installed with the package manager, please don't send me to compile the latest version).

Thanks
