Math trick

[Jaimecbr900]

I got this in via email.

I know it's kinda gay, but I tried it anyway.



1. Grab a calculator.
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

Recognize the number?

That does work.

But the ss# one will leave your middle numbers out....

Birthdate works though.

Is it suppose to be your phone number?

I've done it like six times and got the same answer- not my number.

WTF am I doing wrong?

Ummm, you just left yourself WIDE OPEN.......

You did remember to NOT use the area code, right?

It should work.

Here's one that Tech students are familiar with...and another that actually requires some math skill.

good deal, that shit was crazy

[VooDooXII]

I don't get this math trick by the way...for steps 6 and 7, do you add the numbers together, or each digit?

Say my number's 244 9573...do I do 9 + 5 + 7 + 3...or do I add 9573?

OH!!! now it all makes since... I was adding 1+3+4+7 instead of 1347!

Thanks for clearing that up

And yes Jamie, I knew not to use the area code

obfuscated digit shifting FTW

[shavedcivic]

this is how that Number 23 shit started i bet. crazy as hell.

[BABY J]

We have

XXX
+1
x250
+XXXX
+XXXX
-250
/2

250x80=20,000
/2 at the end makes that # 10,000
first 3 digits x 10000 + last 4 digits
+1 x 250 - 250 obfuscates that, therefore bringing the original number back.

Math Magicz FTW!

[Julio]

I love math tricks.. I know a couple myself. I heard who ever came up with this math tricks must be pretty dumb.....




j/k.. But they must be bored as hell!!!
