Scientific Notation
Scientific notation allows us to represent extremely large or
extremely small numbers in a more effective way. It is written as
a decimal multiplied by a power of 10.
1.59 x 109
Standard Form to Scientific Notation:
1. Move the original decimal point after the first number that is
not a zero.
2. The power of ten = how many places the decimal point was
moved.
Very small number - negative exponent
Very large number - positive exponent
