rules for writing numbers in scientific notation:
1. move your decimal so that the first number is a number between one and ten.
2. the exponent is the number of times you moved the decimal.
3. If you move the decimal to the right the exponent is -.
4. If you move the decimal to the left the exponent is +
.0015 kg = 1.5 X 10 ^ -3 kg
8,002,000 km = 8.002 X 10^ 6 km
