1/1000 or 0.001
10-3 is 0.001
10-3 = 0.001
3 times 10 to the 8th power divided by 7 times 10 to the negative 7th power equates to: 4.28571428571
1 times 10 to the power of negative 3 (1 x 10-3)
The answer would normally depend on the form of the expression: (-10)^3 or -10^3 but in this case they both equal -1000
It is: 6.7*10^-3 = 0.0067
3 * 10-1 = 0.3
10
If you are implying the expression can only have two terms than any expression where the second subtracted negative term is larger than the first negative term would work to give you a negative answer. e.g. (-4) - (-1) = -3, (-10) - (-3) = -7, (-412) - (-15) = -397, etc.

50 x 10-3 = 0.05
10-3 = 1/103 = 0.001
