What? :D

Along the same lines, but in a story to make it more confusing:

3 friends go to a motel and ask for rooms, but there is only one room available for $30/night. The friends split the cost, so each pays $10. The next morning, the manager comes in and realizes they were overcharged as they were running a special and the room was only $25. He sent the front desk clerk to refund them $5. The clerk decided to give them each a dollar back and keep $2 for himself. So after each receiving a dollar back, they each paid only $9.

$9 x 3 == $27 (what each friend paid) + $2 (what the clerk took) == $29. Where did the extra dollar go?

@blockchaintacos eh, the $2 are already part of the $27.

@blockchaintacos as @Fast-Nop already said. The problem is that the room would be 25$ in 3, meaning 8+1/3 each. Now, they're just leaving 2$ tip, which makes exactly 9$ each. It makes it confusing because that 1$ comes from the 1/3*3 that they had paid implicitly!

Also, dividing by 0 makes you achieve every possible results on the rhs :) like Latin said: ex falso sequitur quodlibet - from false premises it can follow everything (as in, being able to divide by 0 is the false assumption!)

Sorry for the cap obvious part 😂

Troll math 😏

Let me ruin it by stating what's wrong: (((((SPOILER)))))

The wrong step is where you cross out the (10-10) in third step from nominator and denominator.. You can't just simply cross out zeroes like this!! (Because it's basically division by 0, twice)
.
It's same as saying:
0/0 = (0*m)/(0*n) = m/n ..

You can do it with any two numbers m and n, and it will give a different answer everytime, this is why it is ""indetermined"".

You also can't do calculations like this, if you're going to calculate 2/3, you can't just say 2/3 = (2*0)/(3*0) = 0/0

And when solving an equation like:
X = 5X, you can't divide by X from both sides unless you're absolutely sure that X can't equal 0

If you do, you will get 0 = 5, which ofc makes no sense.

@blockchaintacos My barber tried to convince me that riddle was something mindblowing when in fact it's just tricky in a stupid way.

I tried telling him that you can't add -27 (net balance of the friends) and +2 (net balance of the clerk) and treat it as +29. You just have to ask yourself how many dollars each party ends up with, and you'll realize it's hardly even a riddle.

Of course my dopey ass barber wasn't having it

it actually seems like a partial solution neglecting the complex ones
