Sort by:

" Any number $$A$$ will be $$0$$ or $$1$$ or $$2$$................or $$m-1$$ modulo $$m$$; which account to a total of $$m$$ different possibilities.

Also; in a series of $$m$$ consecutive integers; two of them cannot have the same result modulo $$m$$ since that would make the difference between them a multiple of $$m$$ and hence total numbers in the series will become at least $$m+1$$. · 10 months, 3 weeks ago

(Continued)

But, since no two share same result modulo $$m$$ and there are $$m$$ numbers and only $$m$$ possibilities hence; each possibility must occur exactly once and hence; all $$A$$ will have one and exactly one number in the series which is exactly the same modulo $$m$$." · 10 months, 3 weeks ago

I got it.Nice explanation;however,i am not getting what do you mean by the same result mod m and exactly same mod m. We are supposed to say with respect to A.Do you mean with respect to A while saying it? · 10 months, 3 weeks ago

I havent yet started modular arithmetic formally so I dont know the exact terns for that;
Same result modulo $$m$$ means leaves the same remainder when divided by $$m$$
Exactly same mod $$m$$ means leaves the same remainder as A leaves when divided by $$m$$ · 10 months, 3 weeks ago
