--Note, if you are using a graphing calculator, do not enter all of the information at once. do each step one by one.-- 1) Ignoring your area code, key-in the first 3 digits of your phonenumber into the calculator 2) multiply by 80 3) then plus 1 4) multiply by 250 5) plus the last four digit of phone number 6) plus the last four digit of phone number again 7) minus 250 8) divide by 2 at last
Oh, that one is easy to figure out... just skip the phone number parts... If you take 81, and multiply by 250, you get 20250. If you subtract 250, you get 20000... If you divide that by 2, you get 10000... And if you take the first part of your phone number, multiply it by 10000, and then add the second part of your phone number, you get... Aha! :lol: btw, if you move the "divide by two" up before you enter the last 4 digits of your phone numbers, you only need to input that once... but I suppose that would look like a phone number at that point... Alright, my mother is a college math professor and it's genetic...
