Addition and subtraction of values in scientific notation. 

Addition and Subtraction

Whenever we add or subtract values in scientific notation we must make sure the exponents are the same value. 

Concept #1: Addition and Subtraction Operations

If the exponents are not the same then we transform the smaller value so that they do.
