"PEMDAS"
P- Parentheses
E- Exponents
M- Multiplication
D- Division
A- Addition
S- Subtraction
Note: multiplication and division are interchangeable. addition and subtraction are also interchangeable. parentheses THEN must stay the same, though.

You memorize the rules that are considered standard.
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.

The various operations within the expression are carried out using the order of operations: BIDMAS (UK) or PEMDAS (US).
Yes, the order in which you perform operations in a numerical expression does matter due to the rules of operator precedence. According to these rules, operations are performed in a specific order: parentheses first, followed by exponents, then multiplication and division from left to right, and finally addition and subtraction from left to right. Failing to follow this order can lead to different results for the same expression. Therefore, it is crucial to adhere to these rules to ensure accurate calculations.

The set of rules that dictates the order of operations in mathematics is known as the "order of operations." It is commonly 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). This hierarchy ensures that mathematical expressions are evaluated consistently and accurately. Following these rules prevents ambiguity in calculations.
There are different rules for different operations.
