Section 14-1
This week in advanced math we started chapter 14. Chapter 14 is all about matrices. Matrices are super easy stuff we learned in algebra 2. We finished up our chapter 4 test on Monday and took a quiz either Tuesday or Thursday on matrices but I can’t remember which day. We also started with this new online math website that is kinda like skills tutor. It’s pretty cool I guess, helped me remember some stuff I forgot from algebra 2. Anyway let’s do some super easy problems on matrices.
Examples:
5 [3 6] = [15 30]
[9 10] [45 50]
*this is supposed to be a 2x2 but idk how to do big brackets so all my examples will look pretty
wack so deal with it.

[1 3] + [2 4] = [3 7]
[5 7] [6 8] [11 15]

Name the matrice

[5 6 7]
[4 1 -3]
[3 -1 -4]
