HSN-VM.C.6
High school — Use matrices to represent and manipulate data, for example to represent payoffs or incidence relationships in a network.
A note on this mapping: HSN-VM.C.6 is a (+) standard — beyond the college- and career-ready threshold, i.e. precalculus rather than Algebra II.
The skill that covers it
What a student should be able to do
- Add matrices, multiply one by a scalar, and take a transpose.
- Multiply two matrices, and give a single entry of a product without computing the rest.
- Decide whether a product is defined and what size it is.
- Recognise the identity and a symmetric matrix, and show that matrix multiplication is not commutative.
