2000 x 2 = 4000

To the lower number, add an irrational number that is less than the difference. For example, if the difference between the two numbers is 0.001 (1/1000), you can add the square root of 2 divided by 2000; pi divided by 4000, or the number "e" divided by 3000, to the lower number.
3000 to 4000 years ago in ancient Mesopatamia
99 = 2 100 to 999 = 900 x 3 = 2700 1000 to 1999 = 1000 x 4 = 4000 2000 to 2999 = 1000 x 4 = 4000 3000 = 4 10,706
3500
It is: 4000 --------------------------- 5000 - 3000 = 2000 and 2000/2 = 1000, so 3000+1000 = 4000 and 5000-1000 = 4000 The easiest way to find the halfway point (the average): add the two numbers and divide by 2.

It was between 4000 and 3000 BCE.
0.5*(2500 + 5500) = 4000
