You need to keep the notations for a random variable and a distribution separate. As such 2*NormalDistribution[m,s] is not a legitimate command. If you want to avoid TransformedDistribution, consider using Expectation.

look up TransformedDistribution in the docs. E.g., try Mean[TransformedDistribution[a + b, {Distributed[a, x], Distributed[b, y]}]]
