A little maths :

(1 - (K11 - L11)/K11) * 100
= (1 - (K11 / K11) + (L11 / K11)) * 100
= (1 - 1 + (L11 / K11)) * 100
= (L11 / K11) * 100

No - it's (K11 - L11) !!!

And also you should check operator precedence !

You should take another base course in math Smile | :)

>(1 - (K11 - L11)/K11) * 100
> = (1 - (K11 / K11) + (L11 / K11)) * 100
Where did the + came from ?

(K11 - L11)/K11 is the same as (K11 / K11 ) - (L11 / K11)

Besides, the parentheses signifies that it should be evaluated first.
the formula is evaluated to;
K11 - L11 then divided by K11, subtract the answer from 1 then multiplied by 100 to represent as a percentage.
This is a valid income formula.
if L11 = 100, K11 = 200, this will result into a 50% answer.

Two minuses make a plus. So yes, as you got, (k-l)/k is k/k-l/k. But the expression is 1-(k-l)/k = 1-(k/k-l/k) = 1-k/k+l/k. The post you were replying to brings the fraction inside and resolves the brackets in one step. (As described earlier, it then further simplifies 1-1+l/k = l/k.)

(1 - (K11 - L11)/K11) * 100
= (1 - ((K11/K11) - (L11/K11))) * 100
= (1 - (1 - (L11 / K11))) * 100
= (1 - 1 + (L11 / K11)) * 100
= (L11 / K11) * 100

Did you got it ?

Whoever set up the spreadsheet originally simply plugged in standard accounting formulas without performing any simplification.

Gross Profit Margin is defined as the difference between revenue and cost of goods sold, divided by the revenue:

GPM = (Revenue - CoGS)/Revenue

The equation in the spreadsheet you were looking at was looking at (effectively):

(1 - GPM)*100

True, it could have been simplified, but there are (at times) reasons for not performing every possible simplification. In this case, to someone who "thinks" in terms of CoGS, Revenue, Margins, etc. the equation given makes a lot of sense. To a programmer (or a mathmatician) it is not very efficient, but to the accountant it provides self-documenting code. This is especially important in Excel, where you can't add comments to the code (cell equation).

It appears that they were trying to calculate the proportion of each dollar of revenue that the company spent as expenses.

To me they are Windows Presentation Foundation and What The F***. So I guess they are the same to me too. Roll eyes | :rolleyes:

Hehe, not heard that one before. RTFM has gone out of fashion though with the elimination of actual manuals to refer to.

It's funny that you used the wrong term ("shorthands"), followed by the correct term ("acronym"). You are consistent in your inconsistencies.

I was about to delete this, but might as well post it here first.

I'm making pac-man.

The Enemy is the "ghost", Hero is "pacman".
When the value of the map[x,y] = 1 it means there's a wall.

Worst thing is that the ghost is still going through walls.

Lesson for today: don't be lazy and design a decent recursive algorithm Sniff | :^)

if (Math.Abs(Enemy.X - Hero.X) > Math.Abs(Enemy.Y - Hero.Y))
            {
                if ((Enemy.X - Hero.X) > 0)
                {
                    if ((map[Enemy.X - 1,Enemy.Y]) != 1)
                    {
