How do you find exponential notation from standard notation?

Exponential notations are ways of writing very large or very small numbers using exponents. The first step is to add or move the decimal point. For a number like 0.00435 you move the decimal to make it 4.35, or for 345,000 the decimal would be 3.45. After moving the decimal you count how many spaces. If the decimal moved to the right then it looks like 4.35*10^-3 and when moving left it would read 3.45*10^5.
