Scientific notation produces convenient numbers when working with very small or very large quantities.
so that we can easy to know the measuring mass of an atom
It's best to convert those numbers from scientific notation to normal notation; that makes it easy to add them. After adding them, you can convert back to scientific notation if you want. Another option is to keep the numbers in scientific notation, but to convert them so that both have the same exponent.
Writing large or very small numbers in scientific notation helps prevent simple mistakes. For example, in physics or chemistry, the number of basic particles in one mole of a substance is Avogadro's number, which is 602214129000000000000000 or 6.02214129*1023 in scientific notation. In the expanded form it would be quite easy to miscount the number of zeros.
Scientific notation is an easy way to handle large numbers and make them smaller so they are easy to handle. The scientific notation for 125.000000000000 is 1.25x10 to the 14Th power.

Large Number & Small Number are Difficult to Write and Read,So a Method For Writing and Reading them More Easily This Calle Scientific notation ,To Computation make easy! :)))

Scientific notation makes it easy to write down numbes, and to compare them (if normalized scientific notation is used). It is also fairly easy to multiply and divide them, once you know what you are doing.

Not as such! Scientific notation is instead a convenient way of working with very large or very small numbers. For example the earth has a mass of 5,974,200,000,000,000,000,000,000 kg. This is quite a difficult number to work with (it takes a long time to count all the zeros and find just how big a number it is!) In scientific notation it is written as 5.9742 × 1024 which is much more easy to work with!
