What is the rule for Pemdas?
You can alternatively apply PEMDAS as schools do today: Simplify everything inside the parentheses first, then exponents, then all multiplication and division from left to right in the order both operations appear , then all addition and subtraction from left to right in the order both operations appear.
Does multiplication always come first?
Order of operations tells you to perform multiplication and division first , working from left to right, before doing addition and subtraction. Next, add and subtract from left to right. ...
Do you always use order of operations?
Always start with operations contained within parentheses . ... In any parentheses, you follow the order of operations just like you do with any other part of a math problem. Here, we have two operations: addition and multiplication. Because multiplication always comes first, we’ll start by multiplying 6 ⋅ 2 .

- So the first thing we do is evaluate expressions within parentheses.
- Next we evaluate terms with exponents.
- Then we multiply and divide working from left to right.
- Lastly we add and subtract working from left to right.
