Chapter – 1 Real number
The Simplest Way to Learn Real numbers!
What is the real number?
• Real number is a value that represents a quantity along a line.
• Real number consists of all rational and irrational numbers.
• The sub sets of real numbers are:
1. Natural number
2. Whole number
§ Natural number - The set of counting numbers, which is also a subset of real no. (N= 1, 2, 3, 4)
§ Whole number - The set of natural numbers including zero. (W=0, 1, 2, 3, 4)
§ Integers - The set of natural numbers, their negatives and zero. (Z=-2, -1, 0, 1, 2)

What is the format of the course?
Our course of CBSE class 10 math chapter 1 is designed to make the concepts simpler to learn and cover all the main topics. Some are:-
Euclid’s Division Lemma
If we have two positive integers a and b, then there exist unique integers q and r which satisfies the condition a=bq + r where 0
Now, to calculate the Highest Common Factor (HCF) of two positive integers a and b, we use Euclid’s division algorithm.
The rational number is also known as a ratio. That means it can be written as a fraction, for example, 456/100= 4.56, 64/8=8
All numbers that are not rational are considered irrational numbers. Irrational numbers are non-repeating digits that don’t end to the right of the decimal point. For example:-
2.55 is irrational number
400 is not an irrational number
