[ ] for matrix and { } for set. I just remembered. What does | stand for? Why = under A and - under b? I am very recently embarking on linear algebra. Btw, I love your presentation, lovely bright pen colours against black background, none of dark colours getting lost into blackness of background. The size of your handwriting is just right for my eyes. Thank you for the tutorial.
= under A means that A is a matrix. | is a representation of representing the equation Ax = b as an augmented matrix. Google it up. Its just a representation.
