Please my first theorem which I want it to be Theorem 1.1 happens to be in Chapter 2 and as thus it reads Theorem 2.1 as opposed what I want. I mean Theorem 1.1, please how can I change this? By always defining what I want in the theorem number and sections.

  • 2
    The (composed) number after “Theorem” is supposed to help readers into finding it. What would be the meaning of the first 1, given that the theorem is in chapter 2?

  • I'm working for someone and he claims since it is the first theorem to appear in the project, it should be tagged Theorem 1.1 despite it appearing on the second chapter.

  • And what about the following theorems?

    @Memristor -- 1.1 doesn't make any sense. Just a single number, 1, would make sense, and then just number equations consecutively through the document. Maybe you could try some logical persuasion. Commented May 14, 2023 at 16:28
  • @egreg. The following theorems can then follow as Theorem 1.2, Theorem 1.3, . . . in that order.

1 Answer 1


This is completely illogical, but the customer's always right. 😉






Some people have weird requirements.

See the numbering of theorem~\ref{test}.

Just remove the definition of \thetheorem if logic becomes active again.

  • Thank you so much, sir. So, how will the Lemma, Examples and the rest will now go?

  • @Memristor It depends on whether they're numbered autonomously or share the counter with theorems.
