Basically you're just multiplying the first three digits of your phone number by 10000 and adding the last 4.  (who says there isn't a purpose for algebra!) |
WOW, I don't know what was more impressive, the little trick or the fact you can use algebra! lol
(BTW - this works with a UK number too but the results come up ???0??? so you just ignore the 0 in the middle but it's still cool!)
