## Homework Statement

Find an example of subspaces W1 and W2 in R^3 with dimensions m and n, where m>n>0, such that dim(intersection of W1 and W2)= n

## Homework Equations

dim(W1+W2)= dim(W1) + dim(W2)-dim(intersection of W1 and W2)

## The Attempt at a Solution

Well what I know for sure is that I have to use the equation dim(W1+W2)= dim(W1) + dim(W2)-dim(intersection of W1 and W2). I'm just really confused on how the subspaces should be. Should they maybe be matrices?
