  1. 2. matrix which is n × n square matrix where the diagonal consist of ones and the other elements are all zeros
  2. 4. a number that is obtained by eliminating the row and column of a particular element which is in the form of a square or rectangle.
  3. 6. is obtained by dividing the adjoint of the given matrix by the determinant of the given matrix
  4. 7. a diagonal matrix that has all the elements in the diagonal equal to each other and the off-diagonal elements are zero.
Down
  1. 1. transpose is equal to the matrix itself
  2. 3. square matrix in which every element except the principal diagonal elements is zero
  3. 5. an operator which can switch the rows and column indices of a matrix i.e. it flips a matrix over its diagonal
