SCIENTIFIC NOTATION

 Scientific notation (commonly referred to as "standard form" or "standard index form") is a way of writing numbers that are too big or too small to be conveniently written in decimal form. Scientific notation has a number of useful properties and is commonly used in calculators and by scientists, mathematicians and engineers.

Standard decimal notation	Normalized scientific notation
2	2×100
300	3×102
4,321.768	4.321768×103
−53,000	−5.3×104
6,720,000,000	6.72×109
0.2	2×10−1
0.000 000 007 51	7.51×10−9

In this practice, you will be converting numbers to and from scientific notation.
