  1. Calculations with numbers written in Scientific Notation

  2. Writing Numbers in Scientific Notation • Move the decimal point behind the first non-zero digit. 3,450,000.  3.45 0.0000436  4.36 • Count how many place values you moved the decimal and write this as your power of ten. 3.45 x 106 4.36 x 105 • Decide if the power of ten is positive or negative. • If the original number is larger than 1, the exponent will be positive. 3.45 x 106 • If the original number is smaller than 1, the exponent will be negative. 4.36 x 10-5

  3. Calculations with numbers written in Scientific Notation • Multiplying numbers written in Scientific Notation: • Multiply the integers. (3.0 x 106)(4.0 x 103) = 12.0 x 10? • Add the exponents. (3.0 x 106)(4.0 x 103) = 12.0 x 109 • Dividing numbers written in Scientific Notation: • Divide the integers. (12.0 x 108)/(2.0 x 103) = 6.0 x 10? • Subtract the exponents. (12.0 x 108)/(2.0 x 103) = 6.0 x 105
