• Arithmetic with scientific notation

  • In order to add or subtract, we must first have common exponents for the x 10^n .

    • If n's are the same for each, add or subtract the M values and keep the "x 10^n" at the end

    • If n's are different, move the decimal in the M value until you have a common n for each, then add or subtract the M's.

  • To multiply

    • Multiply the M values to get the M for your product

    • Add the n values to the get the n for your product

  • To divide

    • Divide your M values to get the M for your quotient

    • Subtract your n values to get the n for your quotient
