<-- is all i can say!

hehehehe...ilad man na bay...thats because ang answer nga imong makuha when you do the said operation is always a multiple of 9..tan awa ra ang 9, 18, 27,... di ba pareha ug symbols tanan..

[leckleck]

it's an equation.

[zengatsu]

its more like

(10x + y) - (x + y) = 9x

x is the number in the 10s place
y is the number in the 1s place

so youll always get the value 9 times the number in the 10s place
which obviously is always a multiple of 9

:mrgreen:
