But if each paid initially 10  dollars in Grand total (10 +10+10=30 - $2 for tip =$28.00  / recieved one dollar back to make their Ten into Nine is - $9*3=27.. would equal 1 dollar missing..

I believe the answer lies in the fact that '0 to 9 equals 10'  just like the year 2001 was the first year of the 21st Century, as so many wanted to think that the year 2000 was the first year of the 21st century, where zero like ten is the last year of the 20th century.

I think??????

I wonder if order of execution in math is used in finances/accounting.  Try 1+1-1*0 with windows calculator in Standard mode and then again in scientific mode.  You'll see what happens.

that number should be marked as (1+1)=2 (1*0)=0 two minus zero is two...
but just the sequence alone looks like the 'tail end' the times part would make anything zero.

Quoting Dan W:
Your problem is that you are thinking in whole numbers. Everything from 0 to 1 is less than a whole number. This means that even though the 21st century began 1 January 2000 the first year was not complete until 1 January 2001.

Your wrong there;  the start of the first year of the 21st Century is 2001 and not 2000,
the year 2000 was the 10th year of the 1990's..

No it doesn't because they didn't subtract 2 from 30, they added 2 to 25 which allowed each to keep 1 dollar.

See above

But if you divide three into 28 and get $9.33 in reality their $ten dollar buying power in paper is only $9.00 in paper where are the coins???

I think it may be a bit late to teach you how to count but I'll make one last stab at it.

They began with 3 $10 notes($30). The man came back with 5 $1 notes ($5). There were never any coins involved unless you left something out.

They gave 3 $10 notes ($30) and received back as change 5 $1 notes ($5). 2 $1 notes were given to the man as a tip. The total out is $27. Each kept 1 $1 note. No coins.

Nope, ,the Bellboy did not give back all their monies. ( as in bold above here 5 $5notes.)
He only gave them 5 One dollar notes and they gave two of those 5 singles as a tip and then divided up the three one dollar notes amongst them one apiece...



You know  I'm only yanking your chain,, as I do agree, but the surface of this scenario makes a good parlor game amongst the young at school..

the problem here is that you did 30-2 = 28.  For the tip it is 30+2 = 32.  and then from the 32 you subtract the $5 rebate from the hotel staff 32-5 = 27.  Still $27 or $9 per person.

Again, you are missing anything less than a whole number.

Think of it this way, 1 Jan 0000 to 1 January 0001 is the first year.

You have bought into the myth that there was a year 'zero'.  There wasn't.  There is a lot of material on this.  Here is one excerpt from one:

The concept of a year "zero" is a modern myth (but a very popular one). Roman numerals do not have a figure designating zero, and treating zero as a number on an equal footing with other numbers was not common in the 6th century when our present year reckoning was established by Dionysius Exiguus. Dionysius let the year C.E. 1 start one week after what he believed to be Jesus' birthday.

Therefore, C.E. 1 follows immediately after 1 B.C.E. with no intervening year zero. So a person who was born in 10 B.C.E. and died in C.E. 10, would have died at the age of 19, not 20.

Which doesn't help you a bit.  If you don't understand how to do the problem long hand, you don't understand it well enough to use a calculator, either.
