Secondly, you need to be familiar with the operation rules of integers, including the addition, subtraction, multiplication and division of integers and the properties and characteristics of integers. This is very important to solve some problems involving integers.
In addition, you need to know the basic concepts and operation rules of fractions and decimals. Fractions and decimals often appear in Olympic numbers. You need to master their addition, subtraction, multiplication and division and their relationship with integers.
In addition, geometry is also one of the important contents in Olympiad. You need to know the names, properties and characteristics of various geometric figures, and how to calculate the perimeter, area and volume of the figures.
In addition, algebra is also an important branch of Austrian numbers. You need to know the concept and operation rules of algebraic expressions, and how to solve linear equations and quadratic equations.
Finally, logical reasoning is also an important ability in Olympiad. You need to learn logical thinking methods such as problem analysis, induction and summary, reasoning and judgment, so as to solve complex Olympic math problems.
In a word, learning olympiad requires a solid mathematical foundation, including four operations, integers, fractions and decimals, geometry, algebra and logical reasoning. Only by mastering these basic mathematical knowledge can we better understand and solve the problem of Olympic mathematics.
