If a= 9990.9 and b= 9886.1. First, convert these to scientific notation. If only three significant digits are allowed in decimal portion (mantisa) of the scientific notation and chopping and not rounding is used, what is a-b?

  • simple math -

    a = 9.9909 * 10^3

    b = 9.8861 * 10^3

    Chopping and not rounding

    a = 9.990 * 10^3

    b = 9.886 * 10^3

    (9.990-9.886) * 10^3 = ?
