  2. 7.10 Scientific Notation Why use Scientific Notation? How to write Scientific Notation All numbers written in Scientific Notation are the product of: A number greater than or equal to 1 but less than 10…AND… A power of 10 If the number is originally large, 10’s exponent is positive. If the number is originally small, 10’s exponent is negative. • Some numbers are so large or so small that they are difficult to read a or write. • Diameter of the solar system:118,000,000,000 km • Diameter of an atom of silver:0.00000000000025 km • Scientific Notation makes it easier to work with these numbers.
