Operations with Scientific Notation
Give an example of a number in scientific notation. Give an example of a number in standard notation.

Operations with Scientific Notation
Option 1 Turn each scientific notation into standard notation Add or subtract The turn your answer back into scientific notation

Operations with Scientific Notation
Another way to add or subtract numbers in scientific notation is to change them to standard notation, add or subtract and then change back to scientific notation.

Operations with Scientific Notation
Option 2 Write each with the same power of 10. Add or subtract Keep your answer in scientific notation

Operations with Scientific Notation
When adding or subtraction numbers written in scientific notation you may have to find the common power of 10. To find the common exponent you may need to move the decimal point the required number of places in each multiplier to change the exponent. The number may no longer be in scientific notation.

Operations with Scientific Notation
Multiply or divided the multipliers To multiply or divide remember to use the product rule or the quotient rule. Make sure your answer is in scientific notation

Operations with Scientific Notation
Another way to multiply or divide numbers in scientific notation is to change them to standard notation, multiply or divide and then change back to scientific notation.
