Introduction
The arithmetic operations cover the topics of the basic arithmetic operations that are used on the numbers, integers and decimals. There are methods to add numbers like downward addition, and carry over. Subtraction of numbers is solved again using downward and borrowing of numbers. Both addition and subtraction can be done on the number line also.
The steps of operations on decimal numbers are discussed here which includes multiplication and division of decimal numbers by a whole, 10, 100 etc.
While doing arithmetic operations on integers, the signs positive and negative of integers are always taken care of always because the final answer may change its sign depending upon the signs of the given numbers.
There is a specific order of operations like BODMAS, PEMDAS, BEDMAS And BIDMAS that must be followed in simplifying the expressions. The names of order of operations vary by country which have been summarised in the following table.
| Name | Countries |
|---|---|
| BODMAS | UK, India and Australia |
| PEMDAS | USA |
| BEDMAS | Canada and New Zealand |
| BIDMAS | UK |
