    Study Notes

    Significant Figures

    • Adding Significant Figures:
      • Example: 12.345 + 6.78 = 19.125
      • Example: 0.0045 + 0.00089 = 0.00539
    • Subtracting Significant Figures:
      • Example: 12.003 - 8.90 = 3.103
      • Example: 0.0019 - 0.0023 = -0.0004
    • Multiplying Significant Figures:
      • Example: 2.345 x 6.78 = 15.9
      • Example: 0.0045 x 0.00089 = 0.000004
    • Dividing Significant Figures:
      • Example: 12.003 / 8.90 = 1.35
      • Example: 0.0019 / 0.0023 = 0.826

    Scientific Notations

    • Adding Scientific Notations:
      • Example: 3.45 x 105 + 6.78 x 105 = 10.23 x 105
      • Example: 2.34 x 10-3 + 5.67 x 10-4 = 2.91 x 10-3
    • Subtracting Scientific Notations:
      • Example: 3.45 x 105 - 6.78 x 105 = -3.33 x 105
      • Example: 2.34 x 10-3 - 5.67 x 10-4 = 1.77 x 10-3
    • Multiplying Scientific Notations
      • Example: (3.45 x 105) x (6.78 x 105) = 2.34 x 1011
      • Example: (2.34 x 10-3) x (5.67 x 10-4) = 1.33 x 10-6
    • Dividing Scientific Notations
      • Example: (3.45 x 105) / (6.78 x 105) = 0.508
      • Example: (2.34 x 10-3) / (5.67 x 10-4) = 4.14

    Dimensional Analysis/Factor Label Method

    • Converting Units: Problems involve converting units of density, speed, volume, area, and length using dimensional analysis.
    • Density Example: Gold density in pounds per cubic inch, given density in grams per cubic centimeter.
    • Speed Example: Miles per hour converted to kilometers per hour.
    • Volume Example: Swimming pool volume in gallons given pool dimensions in meters.
    • Area Example: Square field area in square feet given side length in meters.
    • Length Example: Marathon length in kilometers given distance in miles.
