WebSubtraction as the addition of the opposite. Another way scalar multiplication relates to addition and subtraction is by thinking about \bold A-\bold B A −B as \bold A+ (-\bold B) A+(−B), which is in turn the same as \bold A+ (-1)\cdot\bold B A +(−1)⋅B. This is similar to how we can think about subtraction of two real numbers! WebNov 15, 2024 · $\begingroup$ For square matrices you can check that the determinant is zero, but as you noted this matrix is not square so you cannot use that method. One approach you can use here is to use Gaussian elimination to put the matrix in RREF, and check if the number of nonzero rows is $< 3$. $\endgroup$ –
