Hi....

If

M X+S Y= M M

M S+M Y= Y M

Y X+S X= Y Y

X Y-Y X= M S

S M-M X= X X

.

.

.

Find.....XM?...which number is?..why?

re-write the above equations as numbers, and proove it.

note: all above are numbers!,converted to letters under certain method.

if X Y-Y X= M S, MS must be zero...

I'm confused

[fabpig]

working backwards (to start with anyway)

S M-M X = X X

M - M = 0

S 0 X = X X

X = 0

X Y-Y X = M S

0 0 0 = M S either/ both M or S = 0

Y X+S X = Y Y

X = 0 proved before therefore Y = 0

M S+M Y = Y M

S+M any number as Y = 0

M X+S Y = M M

M 0+S 0 = 0 0

X = 0

Y = 0

M = 0

S = any number

XM - 0

I think wolfgang meant that X Y = X * (10 ^ number of digits in Y) + Y

I was wondering how to write the numbers (1 to 15) with binary method without using 0 or 1 !!

I looked at my windows at home ,having two curtains, so I said,can I do it using these two curtains?

Yes,,,I can !!

If the first curtain was moved to the right,and the second one didn`t change(S),so I`ll get (1)...I gave (X) to this movement,and by moving it to the left(Y),will mean(2),whereas mixing(X) and(Y),(M) will give me (3)(tie the curtain in the middle).

With this method,I was able to write the numbers(1 to 15) without using 0 or 1.
