6106 Processing Data Using Matrices - Quiz

Many of these question are 'self corrected'. This means, you write your response, and then check the result against the answers provided to determine if you know how to do them, or if you need some work. Do them again, and see if you can get the wording correct - or at least compatible - with the responses. Don't write down answers - write down the patterns you see in the answers so you can repeat them on different questions.
