You are a life saver

[@user-563o45]

Thanks for the example, this helped a lot.

[@amrutapandhare5430]

what if we have (3,4) but there's no any element that start with 4 ?

[@ouya_expert]

he mentions this at 5:13 with a similar example

[@mxd8]

A+ Teaching

[@lesliejarweilei5733]

what if there are repeats in the 's composed of r' column? do we only write them once in the final answer?

[@AdamPanagos]

If that was to happen, you'd only write each element a single time; remove any duplicates.

[@rakibrahman93]

A very helpful video thanx

[@ignassablinskas9175]

In the second example you want to find R o T^-1, but along the way you write it was T^-1 o R, is this a mistake?

[@AdamPanagos]

Thanks! Glad you enjoyed.

[@nurhayatimawi6223]

nice video. but I have a question sir. for example for question 2, if we write the answer (4,7),(5,7).... Is it acceptable? it is the arrangement of the number is not important? Thank you.

[@AdamPanagos]

Please note that I had an error in how I labeled the final column in problem 2. The final column should have been R inv(T), not inv(T)R.
However, the elements listed in this final column are correct. The elements are (7,4), (7,5), (8,4), etc. The order of each of these pair is very important. For example, (4,7) is a different ordered pair than (7,4). So, if you were to switch the order this would not be correct.
Hope that helps.
Adam
