Notes
Introduction to numbers:
-
Number is an arithmetical value, expressed by a word, symbol, or figure, representing a particular quantity and used in counting and making calculations.
-
They help us to say which collection of objects is bigger and arrange them in order e.g., first, second, third, etc.
-
With the help of the numbers, we all are able to add, subtract, divide, and multiply.
-
The most common numeral system is the Hindu-Arabic number system, which allows representing any number.
