Spent like an hour watching other videos and reading the textbook. You actually explained it with logic I could understand, thanks so much

I was lost but now I'm found. Thank you so much

Dude you are the FIRST person to explain ANYTHING about subspace. Thank you, this was so much help. Every other Subspace video out there is FUCKED.

This topic was so abstract I couldn't understand what was going on behind the scenes. Like I knew how to get the answer but I didnt know what I was doing. No other video explained the concept or the how. Thise videos just literally said "as long as these 3 conditions are it is a subspace". This video clarifies perfectly what it was I needed. I really don't understand why teachers try to overcomplicate everything.

you are the only person to ACTUALLY explain the logic behind the rules. You're perfect and sent from God.

Much clearer than the other vids I found, tysm <3

Thanks man! I got a final exam coming up and no videos/tutorials helped me. Your explanation was very concise and clear, thanks!

[Lexyvil]

Very useful! Every source I checked, they did not show examples, but explained the theory, which only got me lost. But seeing how to actually test the axioms, that helps! Thanks!

Just saved my ass. I had a quiz I was losing my mind trying to prepare for. You did this so concisely and clearly. Thank you!

[selenav]

I've been struggling with this and with one video, I feel I understand it so much better

[denicapavlova]
