Considering the life expectancy of people back then was quite a lot of years, people may not have died and still had babies (Abram did not have children until he was seventy).
Therefore, we can assume that each person had three children within 3 years time. Within twenty years, those kids grew up and had three kids and so on and so on.
360 million multiplied by 40.0 is 14,400,000,000
300,000,000 x 100,000,000 = 30,000,000,000,000,000
10 thousand multiplied by 150 million = 1,500,000,000,000
200,000,000,000,000
400'000.00
40,000,000,000,000
312,000,000 multiplied by 10,000 is 3,120,000,000,000
1.29 quadrillion
2 million
20 million multiplied by 1 million is 20 trillion (2 x 1013) under the American/modern British numbering system.
1,200,000,000,000,000 (1.2 quadrillion)
12 * 200 million = 2400 million = 2.4 billion.
