Try to solve this fun brain teaser. Cross the river with all of the zombies and humans. The boat can only fit two at a time. Also there can never be more zombies than humans.

My name is Chris and my passion is to teach math. Learning should never be a struggle which is why I make all my videos as simple and fun as possible. I cover all subjects from basic level math through upper level calculus and statistics. I also make brain teaser and Rubik's cube videos for fun.

Try and solve my other brain teasers as well.
