A number line is a line of real numbers can be arranged, according to their value. Each point on a number line corresponds to a real number& each real number has a distinctive (unique) point which corresponds to it. The best example, the number 1.5 (1 1/2) corresponds with the point on a number line which is halfway between 1 & 2.
The points on a number line are said to be as coordinates. The point zero is called the origin. & the numbers to the left side of the origin are negative numbers & the numbers to the right side of the origin are positive numbers. The counting numbers are starting from 1.These numbers are also said to be as natural numbers. Natural numbers are numbers that was a base of the number system. The number line to 20 will help student to understand the basic things in number theory. This type of number line will includes of numbers from 1 to 20.
That is 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19 and 20.
So totally 20 numbers...
