FAQs on Examples : Multiplication of matrices : Part 1 Video Lecture - Mathematics (Maths) Class 12 - JEE

1. What is matrix multiplication?
Ans. Matrix multiplication is the process of multiplying two matrices together to obtain a new matrix. It involves taking the dot product of corresponding rows and columns of the matrices and summing them up.
2. How do you multiply matrices?
Ans. To multiply matrices, you need to ensure that the number of columns in the first matrix is equal to the number of rows in the second matrix. Then, for each element in the resulting matrix, you take the dot product of the corresponding row from the first matrix and column from the second matrix.
3. Can you multiply matrices of any size?
Ans. No, in order to multiply matrices, the number of columns in the first matrix must be equal to the number of rows in the second matrix. If this condition is not met, matrix multiplication is not possible.
4. What is the result of multiplying two square matrices?
Ans. When two square matrices are multiplied, the resulting matrix is also a square matrix. The resulting matrix will have the same number of rows and columns as the original matrices.
5. Is matrix multiplication commutative?
Ans. No, matrix multiplication is not commutative. In other words, the order in which you multiply matrices matters. If A and B are matrices, in general, A * B ≠ B * A.
