Thanks to Bridgette from a previous class for the following math puzzle:
Try this formula and you might just discover math can be interesting.
Ignore your area code & using only your 7 digit phone
number:
- Key-in the first 3 digits of your phone number into the calculator
- Multiply by 80
- Then plus 1
- Multiply by 250
- Plus last four digit of phone number
- Plus last four digit of phone number again
- Minus 250
- Divide by 2 at last
Is the answer is your phone number?
