Best ResponseYou've already chosen the best response.4you can add any number to 0.333.... and create a new number on the real line where would 1000...+1 be on the real line if you can point it out then I will let you call it a number ;)

TuringTest

Best ResponseYou've already chosen the best response.4yeah but there are an infinite number of 3's and 9's so every digit carries a one from the previous decimal place

TuringTest
 3 years ago
Best ResponseYou've already chosen the best response.4there is no last digit, that's why it's an infinitely repeating decimal

anonymous

Best ResponseYou've already chosen the best response.0There is no last digit, I just took a small value

TuringTest

Best ResponseYou've already chosen the best response.4\[0.333\neq0.333...=1/3\]

TuringTest

Best ResponseYou've already chosen the best response.4this is why we don't add numbers with infinite decimals very often; It's ugly, confusing, and entirely unnecessary

anonymous

Best ResponseYou've already chosen the best response.0what do you get when you add 0.9999...+0.3333... without taking 0.99999...=1 and 0.333... = 1/3

TuringTest
 3 years ago
Best ResponseYou've already chosen the best response.4math is about making things as simple as possible, not overcomplicating things and I told you 0.999....+0.333...=1.333... ^ why is this not a 2? because there is another 3 after it, though we did not write it and another after that, and another after that, ad infinitum

TuringTest
 3 years ago
Best ResponseYou've already chosen the best response.4at no point does the decimal terminate, hence EVERY digit carries a 1 from the digit after it

anonymous

Best ResponseYou've already chosen the best response.0But still you just can't neglect a 2

TuringTest
 3 years ago
Best ResponseYou've already chosen the best response.4yes you can because there is absolutely no 2 how many decimal points down would you expect to find it?

anonymous
 3 years ago
Best ResponseYou've already chosen the best response.0Which means it is not equal to 1+ 0.3333....

TuringTest
 3 years ago
Best ResponseYou've already chosen the best response.4it would have to be in the same decimal place as the remaining 1 you might expect by subtracting 10.999... you might say, "well where is the remaining 1?" well, it is literally *infinitely* far down the decimal, which means it ain't there

TuringTest

Best ResponseYou've already chosen the best response.4how do you figure that 0.999...+0.333... is not the same as 1+0.333... ?

TuringTest
 3 years ago
Best ResponseYou've already chosen the best response.4either by grasping the concept that there is no last digit and recognizing that the 1 will ALWAYS carry over from the previous digit, or by representing it as a fraction which is perfectly valid an makes life way easier

TuringTest

Best ResponseYou've already chosen the best response.4I would agree that is a good standard way to think of addition^ but you want to do 0.333...+0.999... in which case you have to observe a pattern, which you seem to be reluctant to accept

experimentX

Best ResponseYou've already chosen the best response.2you can always locate these points on the real line. and if you continue 0.999.... .... to up infinity this is 1 and for 0.33333.... you might think that you can never locate this point on real line. you can actually locate it. and there is ONE and only ONE point on the line i drew. add these distances.

Best ResponseYou've already chosen the best response.0This problem started in the proof of 0.999... = 1

experimentX
 3 years ago
Best ResponseYou've already chosen the best response.2yeah ... it seems that this is not equal to 1 ... but if you continue this up to infinity ... still this is non intuitive. here a short reason to believe. 0.9 ~ 1.1 < let's find a pair of points 0.99 ~ 1.01 0.999 ~ 1.001 < 0.9999 ~ 1.0001 < in similar fashion you put infinite zeros between 1 and the last 1 what would you get 1.00000000000.. infinite zeros.....................1

TuringTest
 3 years ago
Best ResponseYou've already chosen the best response.4to do 0.999...*10 you can either 1) accept that multiplication by 10 moves the decimal place over by one space (it is perfectly okay to utilize that, if we did not utilize powerful concepts as givens then math would be a monstrosity to do!) or 2) add each corresponding digit ten times and recognize that there is not last digit, hence every digit will carry a one from the digit to its right, of which there are infinitely many I strongly suggest option 1

anonymous
