Remainder Theorem
Rule (1)
if a number is form this type (a+1)n / a then the remainder is always 1
Rule (2)
if a number is form of a / (a+1)n then we have two condition
if the power n is even then the remainder is always 1.
If the power n is odd then the remainder is always a-1.
Rule (3)
if the number is this type an + (a+4)n / (a+2) and the n is an even power then the remainder is always 2.
Rule (4)
Lemma theorem:
As the lemma theorem remainder is always equal and less then the divider
d ) a ( q
------------------
r
now the lemma theorem d ≥ r < a
remainder is rqual to divider and less but not greater then a, here one thing is when remainder equal to d remainder is 0 because it divide by d fully.
Rule (5)
Who many possible remainder when we divide any number:
If we divide 12 by 4 then we have only 4 remainder 0,1,2,3 and 4 is also 0.
So the possible remainder is always equal to number and value is 0 to n-1.
