Very kewl Math trick

#1 Postby chadtm80 » Wed Mar 03, 2004 7:23 pm

Here is a math trick so unbelievable that it will stump you.

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

LOOK AT YOUR ANSWER!!!!!!!! WEIRD

If your using a scientific calculator make sure you hit equal (enter) after each line or else it will just do it in the mathmaticly correct order.

Weird and great, as well. Thanks Chad.

When you say this do you mean add the last four TOGETHER?

Example: 555 - 1234 :rarrow: 1 + 2 + 3 + 4

Or, do you mean to add the number the last four make?

Example: 555 - 1234 :rarrow: # + 1234

I see the answer to the trick has been revealed.

The "0" in the first digit on a scientific calculator isn't taken into account. :wink:
