In the world of mathematics, the number lines are considered to be the horizontal straight lines in which the integers will be placed at regular intervals. Every number into a particular sequence can be perfectly represented in the number line and this particular line will extend its self indefinitely on both sides.

The number line is the pictorial representation of the numbers on a straight line and it can be considered as the best possible reference for comparing and ordering the numbers. It can even be utilized in terms of representing any kind of real number that will include every whole number and every natural number. Just to recollect the whole number is considered to be the set of numbers that will include all the counting numbers as well as zero and the natural numbers will be including all the counting numbers without zero. Writing the numbers on the number line is a very easy process so that comparison of the numbers can be carried out very easily and there is no problem at any point in time.

The operations of the numbers can also be explained on the number line very easily. It is very much important for the kids to be clear about locating the numbers on the number nine and zero will always be the middle point of the number line. Every positive natural number will occupy the right side of the zero and every negative number will be occupying the left side of the number line. As the people will be moving on the left side value of the number will decrease for example one will be greater than -2. In the cases of number nine the integers, fractions, and decimals can be easily represented without any kind of problem.

## Important Facts Which the Kids Should Know About the Number Line:

On the number line, the number on the left will always be less than the number on the right

2. Adding negative numbers: Whenever the people will go with the option of adding to negative numbers the resultant will be the negative number for example -2 and -3 will come out to be -5.
3. Subtraction on the number line of positive numbers: Whenever people will subtract two positive numbers for example two from five the result will be positive which will be three.
4. Subtracting the negative numbers: Whenever the people will subtract to negative numbers and will move to the right as far as the value of the second number for example -4 from -2 the result will come out to be +2.

It is very much important for the kids to be clear about all these kinds of things and they should also have a good idea about the whole number and natural numbers as well as basic concepts associated with both of them. Apart from this kids also need to be clear about the concept of parallel lines as well as angle formation of all these kinds of lines so that there is no issue and everything is perfectly undertaken throughout the process.
