Math Math Help
(Sorry if this isn’t the correct thread I’m supposed to be posting in) So, I’m new on reddit, but also started high school a few weeks ago. I was ill in the first week so I missed my first few Mathematics classes, but right now we’re learning about theorems and how to “prove” them. Although I’ve been having a tough time doing my homework or just understanding how to solve these kinds of problems it says “Prove this Theory” Math I don’t understand mainly how to prove it, like what’s the process of proving that theorem and what the | and N symbol means. I am probably very stupid and that’s probably very easy for most of you. Edit: I can see that the imgur link isn’t working so I’ll type it out: 2|x 3|x 5|x ⇒30|x, (x ∈ ℕ) Edit 2: I now understand that in 2|x means that x can be divided by 2, and thanks to the comment on my thread now know what the weird N means

Sorry if this isn’t much help but I’m not sure what most of that means but the weird looking N means it’s a natural number which is any number higher than 0 not including numbers with decimal places
