can i spoil it for you???

 

6 digit no 123456

 

1st 2 digits 12 * 80 + 1 * 250 - 250 / 2 = 120000

 

ie your origional 2 digits with 4 0's

 

adding your last 4 digits twice with the division by 2 at the end gives you your last 4 digits 3456

 

put them together & what have you got??? 123456!! :D

 

sorry to spoil the magic :tongue:
