It is false that the mathematical system in Mesopotamia was based on the number 7. O.
<u>Explanation:</u>
The mathematical system is Mesopotamia was based on the number 60 at it's base and not on 7. This numeral system is known as sexagesimal which had 60 at it's base.
This originated in the 3rd millennium BC and passed on to the ancient Babylonians and it is still used for measuring angles, times, geographic co ordinates. Since the statement that the mathematical system in Mesopotamia was based on number 7 is incorrect.
