  Yes, math can be cool!  Don't believe me?? Well, try out the following problems:
  I. Directions

1.   Think of your age in years

2.      Multiply your age by 2                   

3.      Add 10                                         

4.      Multiply by 5                                 

5.      Add # of siblings you have 

6.     Subtract 50                                   

Look at your final answer; the first 2 digits are your age and the last digit is the number of siblings in your family.  Have someone else try it!  Kind of cool.

  II. Directions
  1. Pick a number, any number
  2. Multiply this number by 2
  3. Add 5
  4. Multiply it by 50
  5. If you have already had your birthday this year add 1753. If you haven't, add 1752. (each year these numbers increase by 1. In 2004, you'd add 1754 if you already had your bithday and 1753 if you haven't)
  6. Subtract the 4 digit year that you were born.
You should now have a number, the first digit(s) being your original number and the last two your age!


  III. Directions
  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

Do you recognize the answer?  Pretty cool.
