  • 1. The Mayans had a number system consisting of shells, dots, and lines. Youcould write up to nineteen with just these symbols. The Maya were one ofthe only ancient civilizations that understood the concept of zero. Thisallowed them to write very large numbers. Would mean 0 Would mean 1 Would mean 5 Maya Numbers 0-19 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19The numbers from 20 on are the same symbols but theyd be 20 times whatthey really represent just add 0 after it. Using this system you can write upto 399.
  • 2. 20 1001. = ____________ 6. = ____________2. = ____________ 7. = ____________3. = ____________ 8. = ____________4. = ____________ 9. = ____________5. = ____________ 10. = ____________Answer key:1. = 2 6. = 4 2. = 7 7. = 9 3. = 15 8. = 5 4. = 11 9. = 6 5. = 1610. = 0To write 20 a zero is placed in the bottom with a dot on top of it, in the second position, the dot in thisplace means one unit of the second order which equals to 20. To write 21, the zero would change to adot (1 unit) and for the subsequent numbers the original 19 number count will follow in the firstposition. As they in turn reach 19 again another unit (dot) is added to the second position. Any numberhigher than 19 units in the second position is written using units of the third position. A unit of the thirdposition is worth 400 (20 x 20), so to write 401 a dot goes in the first position, a zero in the second and adot in the third. Positions higher than the third also grow multiplied by twenties from the previous ones.Examples of the numbers mentioned above follow:
