Determinants and matrices, they look alike. Their similarities caught many unaware and results in "excitements" and much interests.
Both contain numbers within. But ......
 determinants are bounded by two straights lines whereas matrices are by square braces
 determinant resulted in a single numerical value, whereas matrices are sets of numbers grouped within the braces
 determinant can be extracted from matrix, but not the other way round
 there are inverse matrix but not inverse determinant
 a scalar multiplier affects only a single row or single column of a determinant, but affects all the numbers within a matrix
