Help with A Sum
Help with A Sum
I was rolling for A Players Noble Pcs Portfolio and decided to make 2 rolls
The 1st was A 11 then A 6, which means that all her characters portfolio items go up by +60%, but the 2nd was A 3 then A 4, which means that all her characters portfolio items go down by 40%
Can you please work out for me what the total gain is on A +60% increase followed by A 40% loss. Please and thank you. Also this is not lying, it's just not my notorious luck

Re: Help with A Sum
Once again with portfolios. There are other characters whose wealth will not take the game beyond your ability to cope.

But here is how you use a calculator
Wealth increase by 60%
Current value is X (say 120 MCr). Multiply by 1.6, a 60% increase
120 * 1.6 = 192
Decrease by 40%
192 X .6 = 115.2

Thanks but that's a bit hard for me. Anyway my dad told me its +20%. Thanks thoughPsiTraveller wrote: ↑Sun Aug 11, 2019 5:21 pmOnce again with portfolios. There are other characters whose wealth will not take the game beyond your ability to cope.

Why ask a question then reject the answer? You do realise that sooner or later nobody will respond, don't you?

Re: Help with A Sum
Perhaps the question was asked specifically so the answer could be rejected. At what point do we stop assuming good faith?

Re: Help with A Sum
There is a pattern here, of asking then changing the question... or in this case rejecting the answer in favour of one that is simpler but wrong.
I would suggest that if you can't do basic maths on a calculator, trying to play a game that requires it is not a great idea. Learning to do the requisite (and really quite simple) sums would be an answer, or maybe playing a less portfolioobsessed sort of game. But at the very least if you're going to ask a question you should heed the answer.

I believe our friend is playing a different game, and we are all participating in it.

PsiTraveller is correct. First you add the 60% to the base number. Once you have that number you then decrease that number by 40%.
The reason that just a plain 20% is wrong is that the amounts will change. That is, as they say, called math and that's how math works.
Me doth thinks the forum is being played again...
Re: Help with A Sum
Since I don't know if the chart shows percentages, or percentage points, I regard both answers (0.96X and 1.20X) as acceptable.
Re: Help with A Sum
It all depends on how closely you want to align with the facts and reality (aka 'math'):
Assuming you start with 100. Increase it by 60% and it's 160 (100 * .6 = 160).
Then your player takes a 40% hit to their increased portfolio, that drops their 160 to 96 (160 * .40). Or, if you don't like that, multiply 160 * .4, which equals 64. Then subtract 64 from 160, which give you 96. It's very easy to do on a calculator.
If you go with a straight 120% increase that's 120 (100 * .2)
120 does not equal 96.
Math  ruining kids lives since some caveperson figured out counting.

Re: Help with A Sum
I think the problem is the way games use percentages, and not maths itself (although this is more arithmetic; maths usualy means the higher level stuff).
Video games tend to work with probabilities (like 0.5 to hit, add 0.1 per point of Dexterity) but players don't like the decimal point, so they write it as percentage points (50% to hit, +10% per DEX) and that leads to people new to gaming having to ask how percentages are combined and why having 1 DEX gives you 60% rather than 55%.
Outside of gaming, percentages tend to be used conventionally, the way it is traditonally taught in western schools.
For some reason western culture seem to hate arithmetic. Ask who's bad at their native language and almost noone says anything (despite the majority of English speakers being unable to use the apostrophe properly). Ask who's bad at arithmetic and you see lots of people proud to raise hands. In the far east, this does not happen; you'd see almost no hands either way despite there being no genetic difference in ability. It's something about the culture.

Re: Help with A Sum
It's why formulas have brackets, and are clear about addition/subtraction and multiplication/division.

Re: Help with A Sum
Well the link I gave at the beginning of my post can literally do everything he is asking for. You can put in the initial number and the percentage increase. The result is then given. You can then put in a new number and select the decrease percentage and the new result will be shown. No calculator needed.
I've given answers to his questions before, but I think I have reached the limit of my patience. It seems an endless cycle of how to get the board to help with his anime games and spreadsheet progession.

I particularly like the way that the C++ programming language does not define certain things like the order in which function arguments are evaluated. Thus in `f(a, b, c)` where `a`, `b` and `c` are functions themselves e.g `f(a(1), b(2), c(3))`, you have no guarantee about which order a, b, and c are computed in. Which is very amusing when they all change some shared value ... in a random order.
