Candy Math

Happy New Year!

 

If you liked Chocolate Math, then you’ll enjoy this puzzle that I created called Candy Math. Can you figure out why it works?

I’ll give you a hint, I am a math teacher and I love equations.

 

 

 

 

 

YOUR AGE BY CANDY MATH

This is pretty neat.

DON’T CHEAT BY SCROLLING DOWN FIRST!

 

 

It takes less than a minute.

Work this out as you read…

Be sure you don’t read the bottom until you’ve worked it out!

This is not one of those, waste of time things.

It’s fun.

1. First of all, pick the number of times a week that you would like to have candy (more than once but less than 10).

.

.

.

.

2. Multiply this by 4 (just to be bold) .

.

.

.

.

3. Add 9.

.

.

.

.

.

4. Multiply it by 25 — I’ll wait while you get your calculator. (See if you can do it mentally. It’s not that difficult if you think of 25 as one fourth of 100).

.

.

.

.

.

.

5. If you have already had your birthday this year, add 1782 …

If you haven’t, add 1781.

.

.

.

.

.

6. Now subtract the four digit year that you were born.

.

.

You should have a three digit number.

The first digit of this year was your original number (i.e. how many times you want to have candy each week).

The second two numbers are YOUR AGE! (Oh YES, it is!!!!)

.

.

.

.

.

This is the only year (2007) it will ever work, so spread it around while it lasts.

Can you figure out why it works? We’d love to hear your comments.
