Multiplying and Dividing

Multiplying…
  • The general format for multiplying is as follows…
  • (N x 10x)(M x 10y) = (N)(M) x 10x+y
  • First multiply the N and M numbers together and express an answer.
  • Secondly multiply the exponential parts together by adding the exponents together.

  • Finally multiply the two results for the final answer.
  • (2.41 x 104)(3.09 x 102)
    • 2.41 x 3.09 = 7.45
    • 4 + 2 = 6
    • 7.45 x 106

Dividing…
  • The general format for dividing is as follows…
  • (N x 10x)/(M x 10y) = (N/M) x 10x-y
  • First divide the N number by the M number and express as an answer.
  • Secondly divide the exponential parts by subtracting the exponent from the exponent in the upper number.

Dividing…
  • Finally multiply the two results together to get the final answer.
  • (4.89 x 107)/(2.74 x 104)
  • 4.89 / 2.74 = 1.78
  • 7 – 4 = 3
  • 1.78 x 103
