What is the 4 steps in solving simple problems?

Polya created his famous four-step process for problem solving, which is used all over to aid people in problem solving:

1. Step 1: Understand the problem.
2. Step 2: Devise a plan (translate).
3. Step 3: Carry out the plan (solve).
4. Step 4: Look back (check and interpret).

How are IMO problems chosen?

The competition is held over two consecutive days; each day the contestants have four-and-a-half hours to solve three problems. The problems chosen are from various areas of secondary school mathematics, broadly classifiable as geometry, number theory, algebra, and combinatorics.

What is IMO longlist?

The IMO has now become an elaborate business. Each country is free to propose problems. The problems proposed form the longlist. These days it is usually over a hundred problems. The Problems Selection Committee chooses a shortlist of around 20-30 problems from the longlist.

What is IMO (International Mathematics Olympiad)?

IMO ( International Mathematics Olympiad) is known for its tough problems that make people sweat but occasionally, easy problems have been provided across the years. These are problems where you do not need even a paper to solve them. Your imagination is enough for such simple problems.
