Brain Net

Brain Net by Michael A. DiSpezio

Your brain is an incredible piece of machinery. About the size of a squished softball, it contains billions of brain cells. These cells make more connections than all of the phones in the world. It's this huge network that produces your brain power! Want to feel the "brain net" in action? 


Take a look at the drawing below. Your job is to figure out how many different paths can get you across from start to finish. 


You can only move to the right. You can't go back. When you arrive at a "fork," take either the top or bottom route. Start counting.

Answer:

Twenty routes. Although you can chart them all out, there is a less confusing way. Starting at the left, identify the number of routes that can get you to a circle. You can arrive at this number by adding the numbers found in the connecting circles to the left. Keep going until you get to the finish.
