What is scientific notation?
A short hand way of writing very large and very small numbers.
500,000,000,000 = 5.0 X 10(11)
.0000000000245 = 2.45 X 10(-11)
All of the metric system is based on the #10
Everything is either X or / by 10
all you are really doing is moving the decimal to the right of to the left
Quick rounding rules:
0 : does not get rounded
1-4 : round down to nearest tenth
5 : stays the same
6-9: round up to nearest tenth
All numbers are between:
1.0 and 9.95 times (X) 10 ( 1- anything)
only place two #'s right of the decimal
if 2nd # is a zero it can be dropped
if 2nd # is 5 do not round anything
