    why RHS of 1st equation is 1mod10 and not any other choice?

    eduncle-logo-app

    for last digit we take mod 10

    eduncle-logo-app

    because if we divide any term by 10 like 732/10 so we have 2 ...where 2 is last term

    eduncle-logo-app

    2 as a remainder

    if you need last two digit so take mod 100....like 732/ 100 you have 32 ...these are the last two digit of our number
