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

$2.9617×10^13 - $3.98×10^11

= $2.9219×10^13

To find the difference in sizes between the hydrogen atom and the oxygen atom, we subtract the size of the hydrogen atom from the size of the oxygen atom.

0.000000000152 m - 1.2×10^-10 m

= 3.2×10^-11 m

To find the difference in diameters between the platelet and the red blood cell, we subtract the diameter of the platelet from the diameter of the red blood cell.

0.0000075 m - 2.33×10^-6 m

= 5.17×10^-6 m

Therefore, a platelet has a bigger diameter than a red blood cell by 5.17×10^-6 m.

To find out how many more people live in China than in India, we subtract the population of India from the population of China.

1.45×10^9 - 1,400,000,000

= 5×10^7

Therefore, there are 5×10^7 (50,000,000) more people living in China than in India.
