One day, two little boys are wandering the forest. As they wander through the bushes, they trip and fall into a hole.

AAAAAAHHHHH!!!

Woah... Where are we?

Who are you?? This is 2500 BCE and I'm an ancient Mayan.

Please dont eat us!

Dont worry I won't. Come over and let me teach you about some math I discovered!

NO! We hate math!

It's ok! It'll be fun and interesting!

Us mayan use a numeral system of dots, lines, and shells, that can have different values depending on how they are placed.

Ohh I see. So if I had 15 cookies, I'd draw 3 lines, and if i had 16, I'd draw a dot on top of them!

Yes exactly! We were also the first people to develop the concept of "0" Which is a shell in our numerals

Hey, i'm getting hungry. Where's the nearest McDonalds?

McDonalds? What's that?

Oh yeah! We must've landed in ancient times. I wonder what the date is?

It's the 14th day of Ch'en. Do you have something important to go to?

Huh? What's Ch'en?

Ch'en is one of our 18 months on our 365 day calendar called Haab. Each month has 20 days, with one extra month called Wayeb with 5 special days added to it.
