So, there is an answer to this question, but initially it is a ******* to the mind. Three friends have a nice meal together, and the bill is $25 The three friends pay $10 each, which the waiter gives to the Cashier The Cashier hands back $5 to the Waiter But the Waiter can't split $5 three ways, so he gives the friends one dollar each and keeps 2 dollars as a tip. They all paid $10 and got $1 back. $10-$1 = $9 There were three of them 3 X $9 = $27 If they paid $27 and the waiter kept $2: $27+$2=$29 Where did the other dollar go? $30 - $1 = $29

They paid $27 total, $2 of which was a tip. The bill was $25. $25 + $2 = $27 There is no $27 + $2. It's $27 - $2 if you want to move the $2 to the other side of the equation.

Now I am not math wiz but if they waiter gave them back a dollar and the time of day was 12:00pm, wouldn't that mean that the obvious answer would be to subtract the orange from the pear which would leave you with an elephant? Correct me if I am wrong though...

It sat there all along? 3*9 = 27, - $2 the waiter took, so it is $25. I don't see any real problem here.

TOTAL Due: $25.00 3 ten dollar bills are given (30.00 exchange) 3, 1 dollar bills are given back Total exchange: $27.00 Subtract $25.00 outstanding house balance + $2.00 remainder Forward $2.00 remainder value to waitress service (fee) Final debit $0.00 (house balance $25.00, waitress balance $2.00, friends balance $1.00 each of a total balance of $3.00; exchange total $30.00)

Wrong, pi(regardless of how you round it) is just utterly wrong. Tau is the new(old) mathematical constant that is always the answer. http://tauday.com/
