comment What is the difference between the 2 ways to remove percentages?
lol, this was settled a while ago, the problem is when you have live clients telling you the calculation should return a certain result when in fact it should return something else. I am being told it should return 517.50 and on here the consensus answer is 496.8

Ok, I get your point about the 1.2 and I understand that I can do (690)(0.9)(0.95)(0.8), but wouldn't this remove 5% from 621 and not 690. I guess what I am trying to get at is how do handle it when I have a mixture of compound and non-compound percentages.

Also, what is wrong with 690 * 0.9 and then 621 / 1.2 = 517.5?

How does the calculation differ if there are more than 2 percentages 2 remove? For example, my starting value is 690 and in the following order I need to remove 10% non-compound, 20% compound, and another 5% non-compound. I have to do it in this order, I can't remove the non-compounds first

@Arturo, I have mentioned the purpose, input and desired output, but if you need clarification, I will update my post

Arturo, using your first equation above, I will update my post and show you how my how my program is calculating it.

@Arturo, I thought 136.1615 looked funny. I appreciate the help, I will look at your post if I have a question, I will add a comment under it. Again, sorry to be a real pain.

comment What is wrong with this simple equation?
Arturo, I would put +3, but I have to assume the person entering the data might put a -2 and a +5 instead of a +3. Maybe they don't realize that they can combine it and maybe they do. But whether they put +3 or (-2 + 5), I have that part calculating correct. In my program, I am adding them to get +3. The part that is throwing me off is removing the +3% non-compound percent to get back to 100.

continued from my last comment. I have learned a great deal already, although I am not as good in math. Someday I will get better.

comment What is wrong with this simple equation?
Arturo, you are correct. I was just setting up test data. I have updated my post to indicate that I just know the final value and the percentages and flat amounts that were added or subtracted and I want to get back to the initial amount without knowing the original amount. You are correct about the mathematical. My math is not as good, so that is why I am asking all these questions in a flurry. What I meant is that I sort of understand and when I implement my program it works fine, but when I add another adjustment to it, my program fails. I can assure you this though....

There is certain data that I am only given, I will update my post so it is more clear.
