The Liga Matemática began at the 2023 National Meeting of Mathematics Students.
When a team manages to solve a problem, it must immediately announce it to the referee and send it to him for correction.
Both teams should know the result of the correction, although no details will be provided about the reason for the error, if any.
The team that solves all 3 problems first will finalize the score, avoiding a 3–3 tie.
For example, if in a match the score is 2-1 and the first team solves the remaining problem, the final result will be 3–1, regardless of whether the second team manages to solve any of the other two problems in the remaining time.
