The U.S. national debt was $2.9617x10^13 in 2021 and $3.98x10^11 in 1971. Find out how much the debt increased in the 50-year period.
To find the increase in the national debt over the 50-year period, we need to subtract the debt in 1971 from the debt in 2021.
Debt increase = Debt in 2021 - Debt in 1971
Debt increase = $2.9617x10^13 - $3.98x10^11
To subtract the values in scientific notation, we need to make sure the exponents are the same.
$2.9617x10^13 - $3.98x10^11 = $2.9617x10^13 - $0.398x10^13
Now that the exponents are equal, we can subtract the numerical values.
Debt increase = $2.9617 - $0.398 = $2.5637x10^13
Therefore, the national debt increased by $2.5637x10^13 in the 50-year period.
To find out how much the U.S. national debt increased in the 50-year period from 1971 to 2021, we need to subtract the 1971 debt from the 2021 debt.
2021 National Debt = $2.9617x10^13
1971 National Debt = $3.98x10^11
Now, let's subtract the 1971 debt from the 2021 debt:
$2.9617x10^13 - $3.98x10^11 = ($2.9617x10^13) - ($3.98x10^11)
To subtract these values, we need to make sure the exponents are the same:
$2.9617x10^13 - $3.98x10^11 = $29.617x10^12 - $0.398x10^13
Next, we can subtract the two values:
($29.617 - 0.398) x 10^12 = $29.219 x 10^12
Therefore, the U.S. national debt increased by $29.219x10^12 (which is $29.219 trillion) over the 50-year period from 1971 to 2021.
To find out how much the U.S. national debt increased in the 50-year period between 1971 and 2021, we need to subtract the debt in 1971 from the debt in 2021.
First, let's express the debt values in standard decimal notation:
Debt in 2021 = $29,617,000,000,000
Debt in 1971 = $398,000,000,000
Now, subtract the debt in 1971 from the debt in 2021:
Debt increase = Debt in 2021 - Debt in 1971
Debt increase = $29,617,000,000,000 - $398,000,000,000
The difference between these two amounts gives us the increase in the U.S. national debt over the 50-year period:
Debt increase = $29,219,000,000,000
So, the U.S. national debt increased by approximately $29.219 trillion over the 50-year period.
