Explanation / Answer
Rule I: You can only multiply two matrices if the # of columns inthe first is equal to the # of rows in in the second. Rule II: You can only add matrices of the same dimensions. a) F B cannot multiply by B because of Rule I b) T c) T d) F D is singular and cannot be inverted e) Probably False While there is an Identity element for matrix addition,I2 usually refers to matrix multiplication and does notequal the identity for addition.
