UNBELIEVABLE MATH PROBLEM
1. Grab a calculator. (you won't be able to do this one in your head)
2. Key in the first three digits of your phone number (NOT the area code)
3. Multiply by 80
4. Add 1
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?
if you didnt get your phone number then you didn't do it right

Given 555-1111:
x=555
y=1111
((80(x)+1)250+2(y)-250)/2
(80x+1)125+y-125
10,000x+125+y-125
10,000x+y
10,000(555)+1111
5,550,000+1111
5,551,111
It's just restating the phone number and using lots of steps and calculations to confuse the person.

3. 80x
4. 80x + 1
5. 250(80x + 1)
6. 250(80x + 1) + y
7. 250(80x + 1) + 2y
8. 250(80x + 1) + 2y - 250
9. [250(80x + 1) + 2y - 250] / 2
= [20000x + 250 + 2y - 250] / 2
= [20000x + 2y] / 2
= 10000x + y

Ummm, the calculator on the computer doesn't have division... It might be a while before I find a calculator around the house...
I don't know if the calculator doesn't have multiplication or division. It is to small to tell. I can't find a calculator around the house...
