I think 123ronnie321 is looking for – the direct sum, not the union.

Hi 123ronnie321
I don't think that's true. Look at A={(1,0,0),(0,1,0)} and B={(1,0,0),(0,0,1)}, for example.

Let V be a vector space and A,B be subsets of V .
prove that: span (A U B) = span (A) + span (B)
looks pretty obvious but dont know how to prove it using math
