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 # (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?

So you basically take a number and add a certain amount and subsctract the same amount and come up with the same number?

No sir. I do not. The first three digits were correct. The last four, unfortunately, were way off.

Yup, since 250*80/2=1000.

start with a number xyzabcd =( 1000000x+100000y+10000z+1000a+100b+10c+1d)
first 3 digits xyz =100x+10y+z
# multiply by 80
8000x+800y+80z
#add 1
8000x+800y+80z+1
#multiply by 250
2000000x+200000y+20000z+250
#add last 4 digits 2 times
2000000x+200000y+20000z+250 +2000a+200b+20c+2d
#substract 250
2000000x+200000y+20000z+2000a+200b+20c+20d
#divide by 2
1000000x+100000y+10000z+1000a+100b+10c+1d

6922251 * 8 = boobless

Story about a woman with a 69" chest, they were too too too big. She went to five doctors and each one said take one of these pills daily, but instead, she took 8. Overnight, she became boobless.

WHOAH!! cool! and when he says "add the last 4 digits" he means add it as the entire number, not individually. the last 4 digits of my # are "6258", so you add "6258" not "6" then "2" then "5" etc...

it works!!
