8 In base 60 … Any number between 1 and 60 corresponds to the units in our numbers. Getting to 60 in base 60 is like getting to 10 in base 10. We dont need a new symbol when we get to 10, and the Babylonians didnt need a new symbol for 60.

10 What do you think these two numbers are? 2 x x = 133= 208
