Math brain teasers.

Many girls think math isn't always as interesting as science is. I will agree that it doesn't apply to our lives in such obvious ways. Until I find a good math topic, lets play some math games. They are brain teasers, so don't get frustrated if you don't get them. (Answers at the bottom if the question has an answer)

1.Why are some letters above the red line and some letters below?

2. Can you move just 3 pennys and turn the triangle upside down?

cCan you move just 2 tothpicks to make 7 squares?

4. 
   1)  Pick a number between 1 and 10 (including 1 or 10).
   2)  Multiply your number by 9.
   3)  Add the digits of the number created in step two.
   4)  Subtract 5 from the number created in step three.
   5)  Find the letter in the alphabet that corresponds to the number created in step four.
            ex: 1=A, 2=B, 3=C,...
   6)  Pick a country in Europe that starts with the letter you found in step five.
   7)  Pick an animal that starts with the last letter of your country.
   8)  Pick a color that starts with the last letter of your animal.


Your color is ORANGE!


5.
   1)  Pick a number between 1 and 9 (including 1 or 9).
   2)  Multiply your number by 2.
   3)  Add 5 to the number you created in step two.
   4)  Multiply the number you created in step three by 50.
   5)  If you haven't had your birthday yet this year, add 1760 to the number you created in step four.. If you've had your birthday, add 1761 to that number.
   6)  Subtract the year you were born (ex: 1995) from the number you created in step five.
   the first digit of your number is the number you started with and the last is you age!
