    if you have A= amod(x) then you divide the A by x (perfect no. (previous one))ans then remainder-1 is our ans because in modulo system "0" is taken if you have any doubt then feel free to ask we will discuss

    sir i didnt understood this step please explain. this step sir.....

    eduncle-logo-app

    basically I break large no. 259 into small in multiple of 11 so I got cute no. which is 6 here,

    eduncle-logo-app

    since gcd of 6 and 11 is 1 so we know that by gcd thm there exist two integers a and b such that 6a+11b=1. so 6a=1-11b, so 6a(mod11) gives 1 here it is clearly 2

    eduncle-logo-app

    so when we multiply both sides by 2 we get the following in pi after equation 2

    eduncle-logo-app

    I want to write pi=pic

    eduncle-logo-app

    are you got it

    eduncle-logo-app

    sir i understood all those sir i didnt understood how 5th last line came only

    eduncle-logo-app

    (11+1)x=10 mod(11) then how x=10 mod(11)

    eduncle-logo-app

    i didn't got that

    eduncle-logo-app

    how 11x mod(11)=0 i am not getting that. please help in that part

    eduncle-logo-app

    11x is multiple of 11 so when we divide it by 11 it gives remainder 0, as modulo operations

    eduncle-logo-app

    I think you once read modulo operations too

    eduncle-logo-app

    thanks a lot sir
