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.

What do you think these three numbers are? = 70= 80= 130

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

Writing numbers in base 60 You dont have to write base 60 numbers in cuneiform symbols. Look at these base 60 numbers – can you work out what they mean? Can you change these base 10 numbers into base 60? Base Base = = = 680 Base Base

Zero The Babylonians didnt have a separate symbol for 0. This number would have meant = 3601 The zero lots of 60 would have just been a gap. Is this a good way of showing a zero, do you think?
