I've tried multiplying these matrices twice now and I'm coming up with the right answer. How do I set up multiple matrix multiplication?

Do I (A * B) * C to get M?

I did my work on the white board and erased it. I'll snap a picture for my next attempt.

Does anyone have a step by step?

You do 2 at a time, and it doesn't matter if it's (AB)C or A(BC) i think

Blue and purple are horrible in this lighting, and yellow is straight up unreadable

What are you using as a device to write? I got a stylus for my tablet and it's garbage.
