The order of operations can be remembered by the acronym PEMDAS, which stands for: parentheses, exponents, multiplication and division from left to right, and addition and subtraction from left to right. There are no parentheses or exponents, so start with multiplication and division from left to right.Order of operations tells you to perform multiplication before addition. Then add. Simplify 20 – 16 ÷ 4. Order of operations tells you to perform division before subtraction.Ans: Yes, we use the BODMAS rule to get the correct answer even if there are no brackets. If there are no brackets, start solving from ‘order’ or ‘of’ followed by Division or multiplication (whatever comes first from left to right) then by addition or subtraction (whatever comes first from left to right).

What is the correct order of operations in math?
The order of operations is a rule that tells the correct sequence of steps for evaluating a math expression. We can remember the order using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

How does the order of operations work?
The order of operations tells us the order to solve steps in expressions with more than one operation. First, we solve any operations inside of parentheses or brackets. Second, we solve any exponents. Third, we solve all multiplication and division from left to right.
Is Bodmas wrong?
Wrong answer
This would be a really useful algorithm if it worked in every situation but consider the much simpler expression, 1 – 2 + 4 . It contains no brackets, powers, division, or multiplication so we’ll follow BODMAS and do the addition followed by the subtraction: This is erroneous.

Is Bodmas always used?
Yes, even if there are no brackets, the BODMAS rule is still used. We need to solve the other operations in the same order. The next step after Brackets (B) is the order of powers or roots, followed by division, multiplication, addition, and then subtraction.
Does order of operations always apply?
Explanation: You ALWAYS need to follow the correct order of operations, otherwise one expression could have several answers, depending how it was done. This is obviously neither correct nor sensible. In calculations, the strongest operations – Powers and roots are done first.
