Please help provide solution for the following Linear Algebra question parts (a) and (b). How to Prove that V = W1 + W2 but V is not the direct product of W1 and W2? How to Prove that V = W1 ⊕ W3?

Let V =
Mn,n (R) be the set of n x n real matrices. Let W1CV be the set of n x n
upper-triangular matrices, W2 C V be the set of lower-triangular matrices, and let
W3 = {A € M,n (R : Aj = 0 for all 1 <i<j<n}.
(a) Prove that V = W1+W2 but V is not the direct product of W1 and W2.
(b) Prove that V = W1 W3.

Branch of mathematics concerned with mathematical structures that are closed under operations like addition and scalar multiplication. It is the study of linear combinations, vector spaces, lines and planes, and some mappings that are used to perform linear transformations. Linear algebra also includes vectors, matrices, and linear functions. It has many applications from mathematical physics to modern algebra and coding theory.
