Neat-o Calculator Trick!
 

I got this from another site but this is sooo cool.

Ok follow these directions EXACTLY!
1. Get a calculator! It's too hard to do in your head.
2. Put in the first 3 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 by 250
9. Divide the number by 2

Does the last number look familiar? Its your phone number!

NOTE: Due to PEMDAS you cant just add all the numbers and hit enter once you must hit enter after every step!

Lol it was right! woohoo [;

Wow, i didn't think it would work. Whoever discovered this is a genius! Thank you for posting, it was a great way to pass the time! :)

i remember this trick in middle school. there was another one that says loose at the end

Wow cool chris theres another word you can make with an upside down calculator but its a bad word so im not going any farther.

i tried it, it didnt work, maybe cause i did it on my phone calculator?

ah ha, i got it now! nicely done chris

Aren't simple number tricks fun? There's all kinds of things like this...good times

"Due to PEMDAS....."...lol, you in middle school?

Cool calculator trick. Bored at work, so anything is fun right now. lol

Wha? Anyone have a calculator with an enter key?

I was able to do it, but I was confused by that instruction. hehe

Windows calculator steps:
XXX = Prefix
YYYY = Rest of phone#

XXX*80+1*250+YYYY+YYYY-250/2=XXXYYYY
