3.1 + 2(11 - 5) + 7 = 3.1 + 2(6) + 7 = 3.1 + 12 + 7 = 22.1
If you change the order of operations, you will get a different result. The person who wrote the expression had a specific order of operations in mind (using generally-accepted rules), so arbitrarily using some other order of operations is, quite simply, wrong.

Replace the variables with the given values. Then you calculate using the order of operations.
order of operations
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).
The various operations within the expression are carried out using the order of operations: BIDMAS (UK) or PEMDAS (US).
The answers are easy to find, by simply using the procedures, rules, and techniques you learned in the class.
replace the variables with the given values and simplify using the order of operations.
