Chapter 5, ‘Matrices,’ in the AIOU 1429/5405 Code Business Math course, is all about using matrices in business. We’ve got video lessons and study materials on our website, PK JOB Website, to help you understand this chapter. You can also practice with solved self-assessment questions in a PDF file. And here’s an important tip: one question worth 10 marks in the exam comes from this chapter. We want to make learning about matrices easy, so check out our YouTube channel, Asif Brain Academy, for extra support.
