Hello, i would like to ask the following question that has been troubling me.(adsbygoogle = window.adsbygoogle || []).push({});

lets say i have 1/3 = 0.33333333333(3)

it may seem clear that 1/3 - 1/3 = 0, but when operating over the decimals this doesnt seem clear. How can i perform an operation over infinite digits and consider it as finite? If i say 1/3 - 1/3 = 0, then i am saying that i was able to subtract all the the infinite digits, or not?

The same for PI, if i say PI - PI = 0, am i not saying that i was able to subtract all the digits of pi?

Maybe i am missing something, but this has been troubling me =( it would also lead to a contradiction to say that PI - PI != 0 since that would mean that they are not the same quantity, something i just asserted when i wrote them, yet i cant perform their subtraction to check that it is 0 in fact... =S

Thanks in advance
