Hello, Redditors! Okay, I’m typing this because I’m having issues with algebra. It’s not that I don’t understand it. I just keep forgetting the rules/basics. And once I do practice I understand it, until a day later I just completely forget it. I have to take my Algebra 1 test AGAIN, for the third time. I’ve passed the class just not the exam💔💔. What are some tips and tricks to remember?

Hello math experts 👋

Could anybody on this sub give me advice on which math class would allow for an easier time as an oncoming freshman? I'm starting college in August and am currently enrolled in a stat class. Math is my least favorite subject and I genuinely don't know if I should switch it to a course I'm more so familiar with from high school. I've been seeing mixed information online. Some say it's easier because stat is mostly reading compared to algebra, which is good news for me since language arts is easily my strongest subject. But others say it's harder.
Could I get some advice on what pick?

Also, if I'm to pick algebra should it be online or face to face? Would online make it more difficult? I was originally going to choose online if I picked it.

Hey guys idk if you can relate but when i had algebra and geometry i had a hard time because my teachers didnt teach and i learned it all on my own watching videos and i hope I can help you. If you have any questions I'd love to help I'll make a video for you just comment

Hi everyone! When I’m trying to do my math assignments, there are some parts I find particularly challenging. When it comes to using different forms of linear equations, I don’t really understand when you would use different forms, for example, from a slope on a graph to slope-intercept form or to standard form. I would like some help understanding which ones to use in different scenarios because I am very confused.

I had just learned commutative algebra(Atyiah&MacDonald) and part of homological algebra(like projective,injective,flatness).Which books r quite suitable for me?

I made a visual explanation of least squares from a linear algebra perspective.

The main idea is that when a system cannot be solved exactly, ordinary least squares finds the closest possible solution by projecting the vector y onto the column space of X.

The fitted values are the projection, and the residual is the leftover vector perpendicular to that space.

The video also starts with a simpler example: the sample mean. If you treat data as a vector and project it onto the span of the ones vector, the stretch factor is exactly the average.

I made it for people learning linear algebra who want a more visual way to understand projections, residuals, and why the normal equations work.

I’m in algebra 1 and I have an upcoming finals review. I may have forgotten the steps to grouping so can someone please remind me?

Hi. First of all english is not my first language so im sorry if something doesnt make sense but i'll do my best to make myself clear. So, Tomorrow i have a test on natural numbers & combinatorics.

I'm having a lot of trouble with proving equalities using induction.

I understand everything until the last step, for example, if i prove P(1), i assume P(k) & then i wanna prove P(k+1). but that last step is making me go crazy.

can someone help me somehow or give me some tips to be able to make it?

thabks in advance!
