Below are sample questions representative of the exercises included on this worksheet and related Pre CAL.141 Multiply Matrices and Interpret Non Commutativity skill assessments:

Problem 1Difficulty: Mastery

Which statement about non-commutativity is always true?

AEven when AB and BA are both defined, they can be different.

BIf AB is defined, then BA is defined.

CIf AB = BA, then A and B must both be diagonal.

DAB and BA always have the same determinant.

Solution & Explanation:AB means “do B first, then A.” Swapping the order changes the transformation/computation, so the results can differ.

Problem 2Difficulty: Mastery

Let A = [[1, 3]; [0, 1]] and B = [[1, 0]; [0, 4]]. Which statement is correct?

AAB = BA because B is diagonal.

BOnly BA is defined.

CAB ≠ BA because scaling y changes how much the shear adds to x when the shear is applied after scaling.

DNeither is defined.

Solution & Explanation:AB means “do B first, then A.” Swapping the order changes the transformation/computation, so the results can differ.

Problem 3Difficulty: Mastery

Suppose AB and BA are both defined and AB = BA. Which statement can still be false?

AA and B are the same size.

BA is the identity matrix.

CA and B commute for this pair.

DAB is defined.

Solution & Explanation:AB means “do B first, then A.” Swapping the order changes the transformation/computation, so the results can differ.
