Is Your Secret Safe? Think Exponentially
1st: Think and write a secret that you wouldn't want anyone to know about you, aside from a couple of dear close friends
2nd: Think of who those close friends, draw them and write their name under the picture (stickmen will work fine)

3rd: If in one day you tell each of your friends your secret, how many total people (aside from you) now know your secret?
______ total people in ___ day
4th: Now, if the next day each of your friends tell three of their friends, how many people now know your secret (aside from you)? Draw them underneath each of their friends
______ total people in ___days
5th: Now, lets say the following day each of these friends tell three friends. Now how many people know your secret? Draw them
______ total people in ___ days
6th: We can see how fast your rumor can spread right? Theres got to be a better way of calculating who will know your secret.
In Walks Exponents :)
Exponents will quickly allow us to calculate how many people know your rumor
Day 1: 3^1 know your secret
Day 2: 3^2 know your secret (plus your original 3)
Day 3: 3^3 know your secret and so forth (plus your original 9)...
Our equation can be thought of as this
# of people who know your secret = (how many people you tell) raised to the power of (how many people they tell) . As those who are told begin to tell others, the exponent grows. Don forget to factor in the original amount of people :)
Moral of the story? Keep your secrets with you or those you really trust
