Summary: There are certain types of questions that are important in science. The significant question can be studied in terms of their composition and by the logical form of the answers. Thinking is a set of elementary questions that give on the end the answer to a basic question. The important questions are usually questions that briefly refer to as a ``sure", ``who", ``how" and ``why". In the some parts of mathematics, we can write formally in relation to the responses to them.
