why does .9 bar turn out to be 1?

Unfortunately to completely understand this you need to understand the concept of limits and convergence.\nJust see that\n.9bar =.9+.9/10+.9/100+.9/1000+.9/10000        .....\nThis forms a series .\nA series converges if partial sums tend to some limit if numbers of terms is made large.\ni,e if I extend this sum to infinite number of terms the answer is finite.\nIt turns out this is a geometric series and sum is indeed 1.\nYou can understand the method you used by just considering the .9bar as a sum.That is x is a sum.This kind of thing is allowed if series is absolutely convergent.

I think that you have lost a bar code font character... but not sure, never used that.

0.7 can be looked as as 0.70.\n\n0.70    0.35\n\nmult. both by 100\n\n70 is greater than 35

There is no flaw as long as you recognize that .99999 repeats forever.  If you were to end it at some point and subtract, then as a previous poster said, you'd actually get 8.99....1.  But since it repeats, there is always another 9 and so it works.\n\nAnd consider this - if .9999999repeating did NOT equal 1, then there would be another number between them.  What would that number be?\n\n~~~~~~~~~~~~~~~~~~~~\nNo, the number in question is not infinitessimal, it doesn't exist.  You can never get to the end of the string of nines to try and squeeze another number in there :)

4.4.........the zeros cancel themselves otherwise the answer would be 8 but because of decimal point locations, its just 4.4.....\n\n\nhow did u come up with the answer?

1\n\njust do a little bit of trial you will see that the smaller number you use it nears 1.

How does this work?  Is it okay to have a decimal in the middle?\n\nType 1   (Screen says 1)\n/ 3          (Screen says 0.3333333)\nx 3         (Screen says 0.9999999)\n+ 9        (Screen says 9.9999999)\n\n- Jack

(.8+.9)/(1+.8*.9)=.98837c

Working above is good until this step:\n\n2 + 0.8x >0.9(x + 6)\n2 + 0.8x >0.9x + 5.4)\n0.1x > -3.4 ← Symbol error in this line\n\nShould read 0.1x < -3.4\nie x < -34

x=-9 because that means all xs on that line equal -9, making it a vertical line which means it is undefined.

Easiest way to describe it is that it has expressed the formula as 9 + (-7). Register B just holds the value of -7. Simple as that.

what do you mean, 1.2 is not a percentage, how can you round it? it must stay as 1.2 absolute

Math is hard.  Instead of using that handy formula, just use google conversions:\n\neg:\nin google search bar, type \n78f in c

The error is +/- 0.01.\n\nThe value then is: 6.02 +/- 0.01

Maybe because we're in base 10 and 9 is the highest base10 one-digit number? Try other bases, and you might get the same conclusion^_^(E.g. 1 in base2, 2 in base3, 3 in base4, 4 in base5, etc.) Just remember that when you sum them up you are still in that base!!!^_^
