**Numbers**

To start with the topic of maths, today we will study about Numbers.

Now, to start with maths - the first thing you must know is the numbers and category they fall in.

**What is the number?**

A number is a group of the digit. Digit being 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.

**Types of numbers**

1)Natural number - {1, 2, 3, 4, 5.......} is a natural number. It is denoted by 'N'.

2)The whole Number - {0, 1, 2, 3.....} Remember if we include 0 in the set of the number then we will get the whole number.

Note: 0 is an only whole number which is not a natural number.

3)Integers - {..... - 4, - 3, - 2, - 1, 0, 1, 2, 3, 4........} Ok, so in Integers negative numbers are also included.

Positive Integer = +1, +2, +3......

Negative Integer = - 1, - 2, - 3.....

Note: 0 is neither positive nor negative number.

4) Rational Number - It is represented in the form of p/q where p and q both are integers and q ≠ 0

E.g.: 4/2, - 5/3.

When we convert the Rational number into the decimal, it behaves differently.

Terminating Decimal: 1/2 can also be written be like 0.5. That is when we divide 1 by 2 it does end giving 0.5 as a quotient.

Non-Terminating Decimal: 1/3 can also be written as 0.3333... that is when we divide 1 by 3 it will have no end and 3 will be repeated again and again.

5) Real Number - All natural number, whole number, integers, rational and irrational numbers are the real number.

Even Number: All number that comes in the table of 2 or let say all number that is divisible by 2 is an even number. Eg: - 4, 2, - 8 etc.

Odd Number: All number that does not fall in the table of 2 or is not divisible by 2 is called an odd number. Eg: - 7, - 9, 3, 5 etc.

Primary school teachers are as important as bricks in a building. As they are the building blocks to your childs education.

I would say DPS is one school that you would find across all cities of India. It is highly reputed in some cities, while not so much in the others.

Why are primary school teachers mostly women?

Khyati Meena

The Learning Tree

I would say, because primary kids are young and have a certain level of curiousness and naughtiness in them, which needs to be dealt with patience. I do not want to sound feminist, but we all are aware that women are better at handling children at such a tender age.
