The PEMDAS rule gives us the correct sequence for solving a mathematical expression. In PEMDAS rule, operations are performed in parentheses first. we have the equation negative nine minus this whole expression 9x minus six this whole thing is being subtracted from negative nine is equal to three times this whole expression 4x plus 6 now a good place to start is to just get rid of these parenthesis and the best way to get rid of these parenthesis is to kind of multiply them out this has a negative one you just see an minus here but it's PEMDAS Rule. The PEMDAS Rule (an acronym for “Please Excuse My Dear Aunt Sally”) is a set of rules that prioritize the order of calculations, that is, which operation to perform first. Otherwise, it is possible to get multiple or different answers.
We don’t want that to happen. Below illustrates an example where there are two possible answers.

It seems clear that the answer is "no". Now clearly all of the following are multiplications of a and b: ab, (a)b, a (b), (a) (b), etc. But notice that the parentheses make no difference at all in this piece of writing.

Rule 2: Simplify all exponents, working Mixed division and multiplication. Similarly, there can be ambiguity in the use of the slash symbol / in expressions such as 1/2x. If one rewrites this expression as 1 ÷ 2x and then interprets the division symbol as indicating multiplication by the reciprocal, this becomes: 1 ÷ 2 × x = 1 × 1 / 2 × x = 1 / 2 × x.

When you see a math problem containing parentheses, you need to use the order of operations to solve it. For example, take the problem: 9 - 5 ÷ (8 - 3) x 2 + 6 This math problem has parentheses, an exponent, multiplication, division, and subtraction. But don't get overwhelmed — let's work through the equation, one step at a time. First, per the PEMDAS rule, we must simplify what's in the parentheses : Objective: I know how to perform mixed operations with parenthesis, addition, subtraction, multiplication and division. If the calculations involve a combination of parenthesis, addition, subtraction, multiplication and division then.
