Fundamental Operation
Fundamental operation in simplifying mathematical expressions consisting of the same type of operation, we perform one operation at a time generally starting from the left towards the right. If an expression has more than one fundamental operation, you cannot perform operations in the order they appear in the given question. We need follow the rules to perform the operations. Some operations have to be performed before the others. That is, each operation has its own precedence.
Generally, the order in which we perform operations sequentially from left to right is: division, multiplication, addition, subtraction.
This order is expressed in short as ‘DMAS’ where ‘D’ stands for division, ‘M’ stands for multiplication, ‘A’ stands for addition and, ‘S’ for subtraction.
We first need to perform operation of the divisions and multiplications starting from the left towards the right and then perform operation of the additions and subtractions from the left to right.
Some of the examples will help us to understand the precedence of operations of addition, subtraction, multiplication and division.
