Sample Questions

1multiple correct

Which of the following are properties of matrix addition? (Select all correct)

Show answer

Commutative: A + B = B + A, Associative: (A + B) + C = A + (B + C), Zero matrix acts as additive identity

Matrix addition is commutative and associative. Zero matrix is the additive identity. However, matrices must have the same order to be added, not just be square.

2multiple choice

Which matrix is the 2×2 identity matrix?

Show answer

[[1, 0], [0, 1]]

An identity matrix has 1's on the main diagonal and 0's elsewhere. The 2×2 identity matrix is [[1, 0], [0, 1]].

3multiple choice

Can matrices A (2×3) and B (3×2) be multiplied to give AB?

Show answer

Yes, AB will be a 2×2 matrix

Matrix multiplication AB is possible when the number of columns in A equals the number of rows in B. Here, A is 2×3 and B is 3×2, so AB exists and will be 2×2.

4multiple choice

If A = [[1, 2]] and B = [[3], [4]], find AB.

Show answer

[[11]]

AB = [[1, 2]] × [[3], [4]] = [[1×3 + 2×4]] = [[3 + 8]] = [[11]]. This is a 1×1 matrix.
