1000000000 m ÷ 1 m = 1000000000 ÷ 1 = 1000000000
There are 10,000,000,000 nanometres in a decametre.
The equivalent is 1,6.10e-15 moles.
There are one billion nanoseconds in one second.
if you ignore the initial 5times for now there is actually a button for this kind of calculation on your calculator(scientific- but still cheap mine was £10) it is shown as x! in this case 10! is 3628800 and remembering the initial 5times= 18144000 this kind of calculations are used for figuring possible combinations of letters and numbers.

43425326738349 * 1000000000 = 43425326738349000000000
33.3% * 1000000000= 0.333 * 1000000000= 333000000or 333 million
8.1 x 1000000000 = 8100000000
5 x 1000000000 = 5000000000
