The order of operations is a specific sequence to be followed while evaluating math expressions. Following the order of operations ensures that we arrive at the right result every time.
A math expression that has multiple operations can be solved in multiple ways, giving different results. If we don’t follow the order of operations, we will most likely get the wrong answer. Hence, it is important to follow the order of operations while evaluating math expressions.
‘PEMDAS’ is an acronym for parentheses, exponents, multiplication, division, addition, and subtraction. We must simplify an expression in this order to arrive at the right result.
It is quite common to forget about the order of operations while solving math problems. The order of operations worksheets help students get accustomed to the PEMDAS rule, which is to be followed while solving any expression. After solving a number of questions, students will naturally adopt and take care of the order of operations while solving math equations.
Yes, we can swap the position of multiplication and division in the order of operations without changing the result. Similarly, performing subtraction before addition does not alter the result either.
