it should be (scale a + scale b)_vector c = a_c+b*c

I also noticed this on top of page 42 of version 1.0 (06 december 2012) of the printed book; I believe one should read:

The distributive rule with 2 scalars, 1 vector: (n + m) * vecV = n * vecV + m * vecV

rather than:

The distributive rule with 2 scalars, 1 vector: (n * m) * vecV = n * vecV + m * vecV

Thanks for this wonderful book, I enjoy it very much.
