• Odd Positive Integers

Euclid Division Lemma

If a positive integer a is divided by b and remainder r is greater than or equal to zero but less than b. This statement is said to be Euclid Division Lemma.

In Mathematically it can be written as

a = bq + r

0≤ r⋖b

Euclid Division Algorithm

The stepwise calculation to find out the HCF of two positive integers by applying Euclid Division Lemma is said to be Euclid Division Algorithm.

Even Positive Integers

The positive integers which are completely divisible by 2 is said to be even positive integers.

Odd Positive Integers

The positive integers which are not completely divisible by 2 is said to be odd positive integers. 

Now we are able to solve the questions of Exercise 1.1
