So the order of operation for any mathematical equation was formulated in 1912. Some of them include the BODMAS or PEMDAS rules which tell us in which order the operations should take place. For this scenario we will consider the BODMAS rule. BODMAS rule is an acronym to help remember the order of operations in calculations. It stands for, ‘Brackets, Order, Division, Multiplication, Addition, Subtraction. However even though these rules exist, people tend to fight over them again and again even in 2021.
