In the order of operation, what operation is completed first?

Answer 1

In the order of operations, the operation that is completed first is called "Parentheses." The order is often remembered by the acronym PEMDAS:

1. Parentheses
2. Exponents
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

So, whenever you encounter an expression, you should first evaluate any operations inside parentheses.
