REAL NUMBER SYSTEM

This course explains the structure of the real number system and key mathematical skills used in secondary school mathematics. You will learn how different types of numbers relate to each other and how to work with them in practical problems.

The course begins with the difference between real and imaginary numbers. You then study rational and irrational numbers and how they fit inside the real number system. The lessons move step by step through important number sets such as natural numbers, whole numbers, and integers.

The course also teaches practical techniques used in mathematics exams and problem solving. These include converting recurring decimals to fractions, rounding numbers using significant figures, representing numbers on the number line, and working with scientific notation.

By the end of the course you will understand how numbers are classified, how to manipulate them correctly, and how to apply these concepts to solve mathematical problems.
