Numbers and alphabets are the basic teachings that a child learns in the house even before his steps reach the door of the school. This is the main foundation of their learning process. As the child starts going to school, he/she discovers how to spell words and numbers. They learn to differentiate the sounds and pronunciation of the words and numbers. And finally, they understand why do we use numbers and words.
The basic use of numbers is to count things. There are different ways to represent numbers. We can say that there are “5” chocolates on the table or “five” chocolates on the table or we can simply show 5 fingers.
The names of the numbers are very important for every student. It helps them to know the correct pronunciation of the numbers. Also, it draws a clear line between the numbers in maths and their spellings in English. For example, while writing a sentence in English, if we use the names of the numbers instead of numbers in figures, we maintain the difference between English and Maths.

Q1: Who Discovered the Numbers?
Answer: In the Paleolithic age, early humans most likely used to count animals and other everyday objects. To keep a record they by carving tally marks into cave walls, bones, wood, or stone. Each of the tally marks stood for one and each fifth mark was scored through to maintain at keeping track.
This system is perfect for small numbers, but when it comes to working with large numbers it doesn’t really work perfectly- try writing 16,780 using tally marks.

As the early civilizations gradually developed, they came up with better ways of writing down numbers. Some of these systems, including Greek, Egyptian, and Hebrew numerals, were originally extensions of tally marks.
Numerous civilizations developed and with them developed the positional notation independently, including the Babylonians, the Chinese, and the Aztecs.
By the 7th Century, Indian mathematicians on the verge of development perfected a decimal (or base ten) positional system, which could describe any number with only ten unique symbols. Over the next few centuries, the Arab merchants, scholars, and conquerors began to spread it into Europe. Today, we have different types of numbers and improved methods of calculation and keeping records.
Q2: What is the Use of Numbers?
Answer: How will life be without numbers? Numbers have become an inseparable part of the development. We could find the distance between our earth and the moon or the sun and express them using numbers. All the buildings, architectures, machines, business, economy all are dependent on numbers. From small things like counting and keeping records of things to generating formulas and inventing new dimensions of almost everything, we need numbers. Numbers help us to know how much we have grown in population, size, and many more. We would absolutely collapse without the use of numbers because there are so many uses of numbers that we can’t even count.
