0.9999 . . . = 1? It sure seems so.

Alright guys, since you are testing out your math skills...

Pick a number between 1 - 10







Multiply that number by 2







Now add 10 to that number







Now divide your number by 2







Now subtract your origional number

















Keep going...

















Your new number is 5
 
I'll trade you my $9999 dollars for your $10000 three times a day every day for a year. :D

Tell him it does not equal 1 ... because your DAD and YOU SAY SO! And if he doesn't agree with you then he's grounded until HIS kids get out of college (worked for my dad, I'm still trying to figure out how I would have had kids to go to college if I'd been grounded. Mom told me I was my dads son so I would have figured out a way :) )
 
Didn't the Beatles explain that whole "9" thing on their White Album?

The difference between theory and practice is that in theory, it doesn't matter, in practice, it does.
 
This is because we cannot write 1/3 as a decimal, it will be .333bar (meaning out carried to infinity). So .99999bar will approach 1 but depending on the situation may never reach one.


Another conundrum is:
Imagine two object x distance apart. Then they move to x/2. Then x/4. And this continues to halve the distance between the two objects. At any given distance the objects are technically never touching since the distance can again be cut in half again and again.

This is one of Zeno's Paradox
