 Hi and welcome to the session, today we will learn about integers, first of all let us see what are negative numbers, numbers with a negative sign are less than 0, these numbers are called negative numbers, for example minus 5, minus 11, minus 15 are all negative numbers. Now let us see what are integers, that the collection of numbers 1, 2 are called natural numbers between 0 with the collection of natural numbers that is 0, 1, then they are known as whole numbers and the collection of negative numbers with the collection of whole numbers that is 0, 1, 2, 3, 4 and so on with the negative numbers minus 1, minus 2, minus 3, minus 4 and so on, then this collection is known as integers, now in this collection the integers 1, 2, 3, 4 said to be positive integers, 3, minus 4 and so on are said to be negative integers, topic is representation of integers on a number line, now mark a point 0 on it, it is on both sides of 0, like this the line of 0 are positive integers and are marked as plus 1, plus 2, plus 3 and so on are simply 1, 2, 3 are negative integers and are marked as minus 1, minus 2, minus 4 and so on, the point minus 7 on the number line, then we will move 7 points on the left of 0, so here we have minus 4, then here we will have minus 5, 7, so this is the point and if we want to 3 points on the right of 0, we have the point which is less than 0, 0 is less than 1, 1 is less than 2, 0 then positive integers for example will be 1 less than 5, that is will be 1 less than minus 5, that is what are negative numbers, integers, representation of integers on a number line, ordering of integers, what is the successor and predecessor of a number, with this we finish this session, hope you must have understood all the concepts, goodbye.
