1. The Scientific Method
The scientific method is a step-by-step way of solving problems.
You will see different steps, depending on where you look, but they are always similar.

3. Scientific Notation
2.99 x 108 m/s = ,000,000 m/s
Express as your first number, then a decimal, then your remaining numbers. “x 10n” tells you the decimal is actually n spots to the right. If n is negative, you move the decimal that many spots to the left.
Express in scientific notation:
346.46

5. Converting Metric Units
Count the number of exponent steps you need to move. If moving up the chart, move the decimal that many spots to the right, down the chart, move the decimal to the left. Put your answer back in correct scientific notation.
Convert the following:
3.34 x 105 Mg into Kg
1056 cm into m
4.189 x 10-4 ml into cl
g into mg

6. Math operations with scientific notation
Adding/subtracting like exponents
2.1 x 103g x 103g =
Adding/subtracting unlike exponents
3.5 x 102m x 103m =
Adding/subtracting unlike exponents and units
2.5 x 103dl – 1.3 x 102cl =

7. Multiplying/dividing
(2.0 x 102m) x (3.0 x 104m) =
(2.0 x 102m) / (3.0 x 104m) =
(2.0 x 102m) x (3.0 x 104cm) =
(2.0 x 102m) x (3.0 x 104s) =
(2.0 x 102m) / (3.0 x 104s) =
