Okay... I'm going to try to explain this...
We have 10 fingers and we used those 10 fingers to invent the decimal system.
The T Rex dinosaur had 4 "fingers" If they had learned to count it could have been like this..
1 2 3 10 11 12 13 20 21 22 23 30 31 32 33 100
Anyway .. On Thursday I was subbing and I took this picture of cube links and shoes.
