In an expression with both multiplication and division and no parentheses, the operations are performed from left to right. This means that if multiplication comes before division, it will be executed first, and vice versa. Essentially, the order in which these operations appear in the expression determines their sequence of execution.
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.
* is times / is divide + is plus - is minus
Parentheses in formulas are used to establish the order of operations. They help clarify which operations should be performed first and ensure that the formula is evaluated correctly. Without parentheses, the formula could produce a different result than intended.
In mathematics parenthesis must be used when the procedures do not follow the normal order of operations.

When there is more than one polyatomic ion. Calcium Hydroxide is an example. Ca has a charge of 2+ and OH has a charge of 1-. To make this neutral, 2 hydroxides are required. So it would be written: Ca(OH)2. If we didn't use the parentheses, it would look like there was 1 calcium, 1 oxygen, and 2 hydrogens. Obviously this isn't right. That's why the parentheses are necessary.
I believe that, in the absence of parentheses, the order of applying operations is as follows (from first to last):1. exponentiation;2. multiplication and division;3. addition and subtraction.I should say I am not 100 % sure this answer is correct.
