Oh, I see what you're saying now. You need to charge $510.204.
500/98*100 = 510.2040....

(x/98)100
is what it would be written as technically though. if you multiplied first it would give you the wrong answer so you have to put the division in parenthesis.

technically it doesn't matter because division and multiplication at done in order its written.
type 500/98*100 and (500/98)100 in a calculator and you get the same thing.

Actually, those brackets are redundant, you complete the division before the multiplication anyway. Order of operations.

edit: i dont know
i thought you would do division first without parenthesis and that would change your answer
you do division before you multiple.

not always. division and multiplication are interchangeable the same as addition and subtraction are. once everything in parentheses has been completed you then move from left to right in the problem performing the indicated operations as they appear while still following the order of operations--so, multiplication and division will always come before addition and subtraction. if all you have is multiplication and division to begin with, you would move from left to right. besides, order of operations is PEMDAS, so if it is how you say, then multiplication would always come first.
in this case, it doesn't matter which order you do it in, but that won't always be the case. if you have more complex problems, you would definitely need parentheses (they are parentheses and not brackets, btw).

That's misleading to say that they're interchangeable. In this instance, the answers will be almost the same, but out by a few decimal places (if completed in the wrong order)

no, it's really not. that is how it works. it just proves that, in this problem, the parentheses are not redundant and that is why the formula would be expressed in the way MHbound showed.

A common technique for remembering the order of operations is the abbreviation "PEMDAS", which is turned into the phrase "Please Excuse My Dear Aunt Sally". It stands for "Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction". This tells you the ranks of the operations: Parentheses outrank exponents, which outrank multiplication and division (but multiplication and division are at the same rank), and these two outrank addition and subtraction (which are together on the bottom rank). When you have a bunch of operations of the same rank, you just operate from left to right. For instance, 15 ÷ 3 × 4 is not 15 ÷ 12, but is rather 5 × 4, because, going from left to right, you get to the division first.

I used to teach math:
Divide the smallest integer by the rounded sum of the cube root of the denominator.
"Thane", subtract the value of Pi ... or at least have some pie.
Next, calculate the vector of the last, then largest known quotient you squared.
If that's less than zero, you fail, go back to the beginning. Do not pass "GO".
A slide rule may help during the following step:
Access the derivative of your buyer ... either derive it from him with advanced quadratic equations, or just whack him with the slide rule.
You answer may come to you at this point ... but results vary ...
Hope this helped ... I don't teach math anymore ...

The term for this property is that multiplication and division are "commutative".

not sure if you're joking. but adding/subtracting and dividing/multiplying come in the same or in the order of operations. so if a division is expressed first with not brackets then that comes before multiplication. punch 2/4*2 and (2/4)2 in a calculator and you get the same answer.
you're quote actually agrees with this.
