Rules for Changing Exponents If you increase the If you decrease the exponent, increase the decrease the number (move decimal to the left) decimal to the right)

Adding and Subtracting Using Scientific Notation • • If the exponents are the same it’s easy. If the exponents are not the same we have to make them the same.

Rules for Changing Exponents If you increase the If you decrease the exponent, increase the decrease the number (move decimal to the left) decimal to the right)

Multiplying and Dividing Using Scientific Notation • Rule for multiplying: Multiply numbers then add exponents and then multiply the units. • Rule for Dividing: Divide numbers and then subtract the exponents and then divide the units. • Make sure your answer is in Correct Scientific Notation.
