In this video, ACT instructor Stephanie goes through concrete examples of ACT matrix problems.

This is the second part in matrix math on the ACT. I like to call this one the power of reasoning. Now that you have the skills of working with matrices from part one let’s talk about the two types of problems that generally come up on the ACT.

The first one we like to call an element comparison problem, and the second one is a matrix multiplication problem.

Remember, matrix multiplication and also matrix element comparison are the two types of problems you are going to see on the ACT. It’s not likely that you’ll see any addition that we learned in the first video, part 1. It’s certainly not going to be on the test that you’ll need to solve anything with these matrices.

Just remember to do a little reasoning to figure out which elements go with which elements for comparison in which rows go with which columns for matrix multiplication. With a little knowledge and a little reasoning, you’ll be just fine with matrices on the ACT.

What was your biggest takeaway from this video tutorial about examples of ACT matrix problems? Do you have any question for Stephanie and Alexis Avila?
