We found 4 Reddit comments about Schaum's Outline of Linear Algebra, 5th Edition: 612 Solved Problems + 25 Videos (Schaum's Outlines). Here are the top ones, ranked by their Reddit score.
Introduction to Linear Algebra is an excellent textbook. Strang explains things in very simple, "what's the point" terms. This is the only textbook I have ever actually enjoyed reading. There are also quite a few videos of Strang's lectures at MIT where he works out plenty of examples.
Schaum's Linear Algebra reads like an exam review: it highlights the main concepts (without the theory) and presents hundreds of worked out examples.

I've never seen a math textbook as incredible and amazing as that one.
The way determinants are presented (permutations + multilinear algebra!!!!!) is absolutely incredible.
The material on group theory, direct sums, tensor products, etc... is presented at a very accessible level.
Tensors are introduced as elements of tensor spaces rather than introducing tensors as "objects that rotate like tensors" (am a physics student).
Absolutely recommend you buy the amazon copy (14$ - it's extremely cheap!!).
The only possible issue I see is your selection of textbook: Principles of Mathematical Economics - I've honestly never heard of this book.
The graduate school go-to textbook is Mathematics for Economists by Simon and Blume. However, I think this book would be overkill for you, as it is geared towards pure, PhD level, economics. Also, I was in a similar place to you, with respect to mathematical training at one point, and Simon & Blume proved to be too large a leap.
My advice would be to use one of the following books (in order of my preference):
1. Essential Mathematics for Economic Analysis by Sydsaeter
2. Mathematics for Economics
3. Fundamental Methods of Mathematical Economics
They'll bring your basic command, of the basic required mathematics up to scratch AND these books cover linear algebra. You will also then be in a good place to tackle Simon & Blume if you ever need to in the future. Another piece of advice: PRACTISE PRACTISE PRACTISE. For what you are doing, you don't need to have a deep understanding of the mathematics you are using BUT, you do need to be very comfortable with applying the techniques.
So, as you are working through (for instance) Sydsaeter, I would be attempting the related practice questions you find in:
Hope this helps.
P.S. Almost all of these books are available for 'free' on Library Gensis
