When you have y = Xe-3 that's a shorter way of saying y = X * 10^-3. Since multiplication distributes and the e operator only looks for the next number by default, yes, 1e-3 * X = X * 1e-3 = X * 10^-3. Likewise for addition.

Try in command window.. And no need to worry about this result..

It actually means 1.0 x 10 ^(+0.003).
