In this examples, 5000 and 889.9 are written in the standard notation and and are written in the scientific notation.
If the decimal is shifting to right side, the power of 10 is negative and if the decimal is shifting to left side, the power of 10 is positive.
As we are given the US national debt amount to a number.
Now converting this into scientific notation and rounded to the nearest hundred millions dollars, we get:
Hundred million dollars =
(1) US Nation Debt (in US dollars) : $286,330,760,848.37
