Modular Arithmetic

Go Person! Wow the page was well made within days!

The modular arithmetic is presented a little differently than usual: the [math]\equiv[/math] operator is usually used, with statements like [math]29\equiv3\pmod{26}[/math]. This would not fit well in this context because of the definition [math]E(x)=ax+b\bmod{m}[/math].

The current version, however, runs into the trouble that [math] (12a+4b)\bmod{26}=92[/math] is an incorrect statement - the Modulo operation usually gives the smallest nonnegative value that is equivalent.

There is really no easy fix to this problem. The one I'm thinking of is to make a Code Busters/Modular Arithmetic page just for modular arithmetic, so we can go over both definitions and not make the page super long.

The way I see it is that the equation is then simplified into its proper form in the next step. I feel like making a separate page might be too in-depth for this event, since modular arithmetic is really only needed for the Affine and Hill ciphers. --Person (talk) 20:23, 22 August 2017 (UTC)

Um I think one of the links are broken. :P "TheChiScientist (talk) 23:23, 12 June 2018 (UTC)"

It would be helpful if you could point out which link is broken. --Person (talk) 16:26, 13 June 2018 (UTC)
