We use numbers every day in our lives, and they are often called numerals. Without numbers, we wouldn't be able to count things, check the date or time, or handle money. Numbers are used for many purposes, sometimes for measuring, sometimes for labelling, and often for calculations.


The properties of numbers allow us to perform various arithmetic operations, such as addition, subtraction, multiplication, and division. Numbers can be written both in figures and in words. For example, 2 is written as two, and 25 is written as twenty-five. For measuring height, weight, or temperature whether in sports, scores, and timings or for writing phone numbers, house addresses, and bus numbers, we use numbers to make our world easier.

Count real objects like fruits or toys to learn easily. Try counting in groups of 5s or 10s to spot patterns. Notice how numbers are formed, like “twenty-one” from “twenty” and “one.” For quick math, round numbers, for example, 49 + 77, where 50 + 77 – 1 = 126. To find how many numbers are between two values, use last - first + 1. For example, 12 – 8 + 1 = 5. 

The number “zero (0)” plays a vital role in mathematics. It is used as a placeholder in the place-value system and serves as the additive identity in the real numbers. Zero represents nothing or the absence of quantity. For example, if there are three apples and now none are left, we use zero to show that.

In math, there are different types of numbers like:
