To change the order of operations in a mathematical expression, you can enclose part of the formula in parentheses. This indicates that the operations within the parentheses should be performed first, altering the standard order of operations. For example, in the expression (2 + 3 \times 4), enclosing the addition in parentheses as ((2 + 3) \times 4) changes the result.

The use of parentheses allows you to control, or change, the regular order of operations. For example, if you have the expression 4 + 2 * 3, under the normal order of operations, you would perform the multiplication before the addition. To perform the addition first, you just add parenthesis so the expression reads (4 + 2) * 3 instead.
The order in which calculations are performed in a formula is called the order of operations.
It depends on your formula, but you may need them to change the order of operations.
The order in which calculations are performed in a formula is called the order of operations.
If you put in parentheses, you can change the order of operations in many cases, as parentheses come before everything in the order of operations.
Order of Operations
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.
83 + 2 = 85 (Excel formula: =83+2)
They are used to change the order in which arithmetic operations are to be carried out.
No, the order of operations in PEMDAS has not changed. It stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
