Q 1: Why do we use Bodmas?
Ans: The BODMAS rule helps students by an acronym to remember the proper order of mathematical operations – a correct and proper order in which to solve maths problems. Some children use it as a mnemonic (like Richard Of York Gave Battle In Vain is used to remember colours). When a student completes a mathematical number sentence which involves various different methods of operations, then BODMAS helps them to know a proper order which is to be followed to complete them in.
Anything inside the Brackets should be completed or solved first, then the orders, followed by any of the division or multiplication mentioned and which is finally followed by addition or subtraction. They are very useful for making difficult expressions easier to understand. Unlike the original mathematical rules, such as associativity of addition or distributivity of multiplication over addition, they are not hard and fast rules.
