# reset counter with thmtools

I am using thmtools to display theorems in a document. The theorems are numbered within a counter that is called 'entry' (this counter is defined within a command that is called 'entry' as well). So for the moment I use:

\declaretheorem[style=theorem,within=entry,name={}]{thm}


and an example of a displayed theorem is given by:

Theorem 2.3 -- Blabla

However, I want my theorems to be numbered just by one single number that is reset whenever I start a new entry in my document (by applying the entry command). So basically I want to get rid of the 2 in the numbering of the example above (which is referring to the entry counter).

• in your preamble, add \renewcommand{\thetheorem}{\arabic{theorem}} after \declaretheorem. – barbara beeton Jul 2 '16 at 16:09
• remove the within=entry and say \setcounter{thm}{0} in your \entry command? – user31729 Jul 2 '16 at 16:09
• Perhaps a compilable document would also be very useful to provide more help! – user31729 Jul 2 '16 at 17:34
• The solution proposed by barbara beeton worked! Since it is not posted as answer I can't vote for it. – AYK Jul 2 '16 at 17:44

\renewcommand{\thetheorem}{\arabic{theorem}}

after \declaretheorem, when you are using thmtools; if you are using a different theorem package, this same command can (usually) be used, again, after \newtheorem definitions or the equivalent.
