Scientific notation is real.
To convert a number in scientific notation to normal form: · If b is positive, move the decimal point b places to the right in the number a – adding 0s at the end of the number, if required. · If b is negative, move the decimal point b places to the left in the number a – adding 0s immediately after the decimal point, if required. · The final expression has the same sign (+ or -) as a in the scientific form. For example: 4.56*10^5 = 456000. -4.56*10^5 = -456000. 4.56*10^-5 = 0.0000456
Scientific notation is useful for very large or very small numbers. If you use such numbers in your "real world", then scientific notation will be very useful. This may be the case, for example, when you work in science or engineering. Otherwise, if you don't work in an area that uses such large or small numbers, you probably won't find much use for them.
When working with really large or really small numbers.
Yes but large numbers like this are usually expressed in scientific notation.
Round a number to a quantity of significant figures that you provide. Enter whole numbers, real numbers, scientific notation or e notation.
Scientists? It's handy for writing out any large numbers...

It helps simplifies large numbers. If your occupation requires you to deal with million, billions, trillions, or larger, then scientific notation saves a lot of time and confusion.
Scientific notation is a short hand way of expressing numbers that are very large or very small such as 10,000,000 = 1.0*107 or 0.0000001 = 1.0*10-7
In both notations a number is represented in the form a*10^b where a is a real number and bis an integer.In scientific notation, 1
It is used for recording very large or very small numbers. This is particularly true for sciences.
Scientific notation is a way to write very large or very small numbers using exponents. For example 2000 is 2x103 . We can do the same thing with negative exponents and write very small numbers like 1/2000 which is 2x10-3 . So one real life use of exponents in in scientific notation.

The so-called "real numbers" are simply numbers that permit decimals. Think of them as numbers in scientific notation, which allow very big or very small exponents (somewhere in the range of -300 to +300), and about 15 significant digits. Since their precision is not unlimited, they do not exactly correspond to what is called "real numbers" in mathematics.
