The US national debt was 2.9617 * 10 ^13 and 2021 and free 98 * 10 ^11 and 1971. Find out how much debt increase in the 50 year peirod.

Answer 1

To calculate the increase in the US national debt over the 50-year period from 1971 to 2021, we subtract the debt in 1971 from the debt in 2021.

Debt in 2021: 2.9617 * 10^13
Debt in 1971: 98 * 10^11

Debt increase = Debt in 2021 - Debt in 1971
Debt increase = (2.9617 * 10^13) - (98 * 10^11)

Let's simplify the calculation:

Debt increase = 29.617 * 10^11 - 0.98 * 10^12
Debt increase = 29.617 * 10^11 - 9.8 * 10^11
Debt increase = (29.617 - 9.8) * 10^11
Debt increase = 19.817 * 10^11

Therefore, the increase in the US national debt over the 50-year period from 1971 to 2021 is 19.817 * 10^11.
