 is there any lesson learnt? may be we can have something build as an extension to markdown4j otherwise people will have to mix %md with angular ?On Sunday, June 28, 2015, IT CTO <[hidden email]> wrote:Thanks Richard! that worked for me!On Fri, Jun 26, 2015 at 2:14 AM Richard Kuo <kuotie@...> wrote:thank youOn Thu, Jun 25, 2015 at 11:02 AM, tog <guillaume.alleon@...> wrote:HiI am not sure mardown4j which seems to be used in Zeppelin does support mathematical expression.You might want to try angular + http://www.mathjax.org/CheersGuillaumeOn 25 June 2015 at 18:38, Richard Kuo <kuotie@...> wrote:''' (under ") is not same as  (under ~), which one you used.On Thu, Jun 25, 2015 at 10:09 AM, IT CTO <goi.cto@...> wrote:I get the same problem with trying to add code notation like ''' in markdown Is this a problem of the md interpreter?On Thu, Jun 25, 2015 at 7:40 PM Richard Kuo <kuotie@...> wrote:I am new to Zeppelin.

## Re: How to enter math formula in markdown

 I guess a %mathjax interpreter which does the %angular and %md work is what you are looking for. This drives us back to the "Discussion about Zeppelin Interpreters maintenance" [1] where no conclusion has been drawn on the zeppelin-extras or zeppelin-contrib (whatever name you give).

## Re: How to enter math formula in markdown

 That's a bit more a consequence of my question.                                                  It is certainly a very good idea for the Zeppelin team to ask themselves which are the core interpreters that they are going to maintain and which are the one which will remain external contributions (with their own lifecycle).I would second the idea of a wiki page collecting the following information:   - the core Zeppelin interpreters (i.e. maintained by the Zeppelin community)   - the "external" interpreters with a link to their websites - and notes on how to integrate themIn addition, it might be a good idea to decide which are the Spark, Hadoop, ... versions supported. Supporting them all will soon be a burden I guess.As this point in time, the community is very active and vibrant (a big thanks to all the people contributing to Zeppelin)  but I see a risk at not being enough focused as this will spread to much the available resources.my 2 centsGuillaume   On 28 June 2015 at 11:06, Eric Charles wrote:I guess a %mathjax interpreter which does the %angular and %md work is what you are looking for.
