Why should I study 『Four Arithmetic Operations for Rational Numbers』 in advance?
Elementary and secondary mathematics use different ranges of numbers.
Since the range of numbers covered in secondary mathematics is rational numbers, including negative numbers, learning rational numbers is an essential first step in starting secondary mathematics.
In particular, elementary school students find it difficult to calculate positive and negative numbers because they get confused between the plus (+) and minus (-) signs in front of numbers and the addition and subtraction symbols.
Therefore, you need to firmly establish the concept of rational numbers and learn the four basic operations for rational numbers so that you can become familiar with mathematics even when you go to middle school.
