Another theorem

I created another theorem . If u wanna ask something leave a comment.


If x is a number with N digits where N>1 then the sum of ' the difference between x and its mirror reverse' and its mirror reverse will be a multiple of 9.

Ex.647
746 - 647 = 99 or 099
99 + 99 = 198
or 99 + 990 = 1089



ADIEU !!!!!

Cool theorems i discovered

well u wont believe it but i discovered 3 mathematical theorems. well over a period of 2 yrs cos wid exams in between terms u can only study

1. if x, n are any natural no.s then sum of digits of (x+1) = sum of digits of ( x+ (10 to the power n ) )

2. if a, b and n are any 3 whole no.s and n >2 then there is NO such whole no. c such that
(a to the power n ) + (b to the power n ) = (c to the power n )

3. if a and b are 2 consecutive perfect squares and b>a thenb - a = root a + root b
if b and a have 1 perfect square between them then
b - a = 2(root a + root b)
and so on...
