Matrix Elementary Operations- HELP I am writing this out of pure frustration now. I have been studying for GATE (mech) regularly for the past month, using HK Dass's Advanced Engineering Mathematics. (context: GATE is an engineering postgraduate exam in India). I have completed linear algebra last week, and yet, there is one topic I absolutely cannot get good at- elementary row and column operations. Usually, there is a target. Sometimes, we aim to reduce to an upper triangular matrix, or REF, or RREF, etc. I understand this part well. I understand the rules, but I do not understand how and when to use them. Each question's solution makes sense, but when I try to do a question on my own, I'm lost. It's a collection of numbers! How do I just know when to do what operation? Every resource I can find online just explains the rules and starts using them. But how do you know where and when to do what? There are too many possible combinations! Please help. I think I'm going insane over this.…
