Bologna Mathematical Competition - Round 4 of the competition, which is held annually in April, aims to assess the mathematical skills and problem-solving abilities of students across various age groups. This year's round saw a significant increase in the number of participants compared to previous years, with over 250 students participating.

The event started with a series of rounds designed to test the candidates' knowledge of basic mathematics concepts such as algebra, geometry, and trigonometry. The rounds were divided into two main categories: Problem Solving and Analysis, where the candidates had to solve complex problems using mathematical techniques and logical reasoning.

One of the most interesting aspects of this round was the inclusion of mental preparation strategies. These strategies aimed to improve the candidates' ability to think critically and creatively when solving problems. Candidates were given a set of questions that they had to answer without knowing how to solve them, and then asked to analyze their answers and identify any errors or mistakes.

Another important aspect of the round was the use of virtual reality simulations. Participants were presented with a scenario that required them to apply mathematical principles to solve a real-world problem, and then interactively simulated the solution using VR technology. This allowed candidates to practice applying mathematical concepts in a practical setting, and also helped them develop critical thinking and problem-solving skills.

Overall, the Bologna Mathematical Competition Round 4 was a highly successful event, with over 100 candidates from different countries participating. The mental preparation strategies used by the competitors were particularly effective, as they helped them to think more analytically and creatively while solving complex problems. The event provided an excellent opportunity for students to practice their mathematical skills and develop their problem-solving abilities, and it will undoubtedly have a lasting impact on their future academic careers.
