Learning about matrices

[amber crane]

I recently joined a study group about group theory and one of the things i have to know is about matrices, i think i have 1 week.

Is there any recommendations for any good (and free) websites or videos? Please tell me if there is.

And if you have more time, i hope you guys can just teach me. That might be faster.

Thanks :)

(what tags should i put in this)

u can find a book such as linear algebra by jim hefferon to get started with matrices 🙂

if u have any questions feel free to ask

ur tag would be matrices & vectors since ur studying linear algebra

khan academy linear algebra is probably more close to what you are looking for

you don't need everything from here to do group theory

but it's certainly helpful

well, they told me that can help, and I don’t mind learning more stuff :)

[rose garnet]

it will definitely help
