5. MULTIPLY BY 250
6. ADD THE LAST 4 DIGITS OF YOUR PHONE NUMBER
7. ADD THE LAST 4 DIGITS OF YOUR PHONE NUMBER AGAIN.
8. SUBTRACT 250
9. DIVIDE NUMBER BY 2
DO YOU RECOGNIZE THE ANSWER?

so easy.
1*250 = 250, subtract 250 = 0
80*250 = 20000
20000 /2 = 10000 which just moves your first three digits over 4 digits. gasp.
last four digits of your phone number + last four digits of your phone number = 2*last four digits. divide that by two and you get... last four digits of your phone number
so in essence, that problem had you:
take the first three digits of your phone number, multiply by 10000, and add the last four digits of your phone number. 5th grade math.
