... Note that even though A has a row of zeros, AT A does not have a row of zeros. Moreover, A is a 4 × 3 matrix, so det A is not defined. (b) (3 points) Your friend (who, sadly, is not enrolled in Linear Algebra) claims that there is no such thing as 4-space, and thus, there is no such thing as a 3-box ...

Scalar Multiplication is multiplying every element in a matrix by the scalar number. *To multiply matrices A and B, the number of columns in A must equal the number of rows in B. The product matrix has dimensions of the number of ...

... Adding two matrices is also done entry-by-entry. If A = (aij ) and B = (bij ) are two m × n matrices, then their sum is A + B = (aij + bij ). That is, the i, j-entry of A + B is the sum of the i, j-entries of A and B. It is important to note that is is only possible to add two matrices if they have ...
