Class 10 Maths Chapter 1 Real Number Notes

CBSE Class 10 Maths Chapter 1 Real Numbers Notes are provided here in detail. As we all know, any number, excluding complex numbers is a real number. Positive and negative integers, irrational numbers, and fractions are all examples of real numbers. To put it another way, any number found in the real world is a real number. Numbers can be found all around us. Natural numbers are being used to count objects, integers are used to measure temperature, rational numbers are used to represent fractions, irrational numbers are used to calculate the square root of a number, etc. These various types of numbers form a collection of real numbers. Here, we are going to learn what is a real number? Euclid’s division algorithm, fundamental theorem of arithmetic, methods of finding LCM, HCF and the complete explanation on rational and irrational numbers with examples.

Real Numbers

Positive integers, negative integers, irrational numbers, and fractions are all examples of real numbers. In other words, we can say, any number is a real number, except complex numbers. Examples of real numbers include -1, ½, 1.75, √2, and so on.
In general,

Real numbers constitute the union of all rational and irrational numbers.

Any real number can be plotted on the number line.

Euclid’s Division Lemma

• Euclid’s Division Lemma states that given two integers a and b, there exists a unique pair of integers q and r such that $a=b\times q+rand0\le r<b$.
• This lemma is essentially equivalent to dividend = divisor $\times$ quotient + remainder
• In other words, for a given pair of dividends and divisor, the quotient and remainder obtained are going to be unique.
