Surely you don't think supreme executive power derives from a mandate from the masses?
As opposed to what, a farcical aquatic ceremony?
That was unexpected.
No one expects the python imposition!
I thought we were an autonomous collective
This is far too useful to be a shitpost.
I know right. I even open the calculator app to verify before committing to memory this nugget.
Barely, only if you choose round and small numbers. 67% of 347 or 347% of 67 which one is easier?
347 is pretty damn close to 350.
350% of 67 =3.5 x 67 ~ 180+21+33=234
SPEAK ENGLISH! Jeez

Yo what
So 50% of 50 is the same as 50% of 50. Both equal 5
And the other half is 0! 5 0
0! is 0.
Edit. I remembered wrong. Keeping it like this as it is funnier that way.

Multiplication is commutative.
50% of 6 == 50/100 x 6 == (50 x 6)/100 == 50 x 6/100 == 6% of 50.

taking x% is just multiplying by x/100, and multiplication is commutative. x% of y is just y×x×1/100, which is the same as x×y×1/100
you can also ignore the % and divide by 100 at the end. for example, what's 5% of 5? that might take a minute to work out. what's 25/100? you instantly know it's 1/4
Percentages can be expressed as multiplication and multiplication is commutative (the order doesn't matter).
Fuck. I had to calculate 4% of 7 a few minutes ago and didn’t know this. I say fuck because it wouldn’t have helped me anyway.
6% of 50
6/100 * 50/1
(6 * 50) / (100 * 1)
(50 * 6) / (100 * 1)
50/100 * 6/1
50% of 6
Works for multiplying any fraction, not just percents.
2/3 of 5 is the same as 5/3 of 2.
2/5 of 7/8 is the same as 7/5 of 2/8.
Everyone’s talking about this math. I’m wondering about the panzer.
They said the water could reach up to 50% of its 1.7 meter height before causing problems, panzer tried calculating 1.7% of 50 meters from head, this is the result.
I was waiting in a car in front of a math tutoring building and was doing the math problems advertised on their window (as one does, of course) and the 7% of 250 is indeed probably easiest as 250% of 7, aka 2.5x7, which is 17.5.
I did it a few other ways, though. 7% of 1000 is 70, then divide by 4 for 17.5. Well, more like, divide by 2 for 35 and again for 17.5, but yeah... mental math is fun.

Let's try this on a sale item. Hmm, let's see, the sign says 25% off $6.99. So that's the same as, let's say, 7% off $25. Oh, yeah, that is much easier. /s
Wait...
So 25% off $100... is 100% off $25! Trollface
I mean if you remove the word off it works. 25% off $100 is $25 100% of 25 is 25 it's still reversible you just let the word off confuse you
You could also make sure to carry “off” to both sides when you swap:
25% off of $100 is 100% of $25 off

Another counter-intuitive percentage fact: A 10 percent discount and a 10 percent fee can be calculated in either order but they don't cancel out.
Example, 90% of (110% of 10) = 110% of (90% of 10). But neither of those is evaluates to 10. They evaluate to 9.9.
For any percentage X, and any base value C, (100 - X)% x ((100 + X)% x C) = (100 + X)% x ((100 - X)% x C) = (100 - (X^2/100))% x C

Great for calculating tips!
Let's see: the bill was $138.72, so I just need 138.72% of 20. And we can subtract 100% and just add the 20 back at the end, then convert the percentage to a decimal so (.3872 * 20) + 20 = 7.744 + 20 or $27.74.
Easy!
I prefer taking 10% and doubling it for a 20% tip.
Take the total, moved the decimal one digit to the left, double it and round to the nearest dollar. I round up at the beginning and end as well which is either close enough or a dollar high if the change is small enough.
$138.72 > 139 > 13.9 > 27.8 > $28
Close enough!

I always just do 10% (easy because you move the decimal one place) and then either double that or add half of it to itself for a 15-20% tip.
For sure. Reversing the percentages here makes this far more difficult. I just felt we needed to shittify this post a little.

Oh panzer of the lake, why am I still single?
Are you sure you can stand the answer?
True mathematics derives from established mathematical theory, not some farcical aquatic armored vehicle!

How is 17% of 83.27 easier then 83.27% of 17?
Oddly, yes.
Percentages also add together in partials. As in 10%+5%+2% = 17%
So, you start with the 10% by moving the decimal over 83.27 becomes 8.327
Then add half of that (5%) to its self and get 12.49 (rounded)
Then take the 10% number and move the decimal over once more (1%) for 0.833 and double it (from 1% to 2%) and get 1.666 and add that to your running total to get your answer of 14.16 (rounding)
And when I calculator check this I got 14.1559.
I hate math so much.
Thank you for this
It was recently discovered that all AI everywhere was connected to the Panzer all along. /s
In either case I would multiply 5 by 6 and move the decimal. Interesting though.

Just always convert the percentage to a decimal, and it’s easy either way.
0.06x50 is as easy as 0.5x6. They’re both just 5x6.
All these comments like “What about 47% of 3.11?” Well, yeah, of course it’s harder to multiply two- and three-digit numbers than it is to multiply single-digit numbers.
