Looks like I'm going to get the book by Dudley. Thanks to everyone for the suggestions, it was really helpful.

I saw the book on amazon (the second version) and it does seem to take time to get to number theory. I would like to self-study it, but I don't know if I'm going to have that much time for it because the reason I'm looking for a book on number theory is that our school books are terrible and...

Well, I suppose since I do want to learn the subject without any gaps, I mean if it is more beneficial, then why not?

Well, I have an understanding of basic high school algebra and geometry, some rudimentary linear algebra (2x2, 3x3 and their properties, and solving system linear equations), basic trigonometry (we are going to start learning about the graph of trig functions soon) and etc. Well I want it to...

Thanks! I'll look into it, but I'd prefer studying from a book written in a somewhat self-study fashion. I'm not so big on watching videos.

Hello, I'm looking for an introductory number theory book for high school. Any recommendations are welcome. Thanks.

Yes, I see now, I thought I could solve the equation by taking the log of both sides, but seeing as that is a mistake I'll try and work it out another way. Thanks!

So, taking the log of both sides of this equation would be more like this? And would it be useful in this case?

So, recently I have been learning about logarithms and how to solve exponential equations with the help of logarithms, but I am curious if I can take the log of both sides of an equation like this in order to solve it? If not, then could someone explain why? Thanks.

Oh, now I see. Well thank you and everyone else for clarifying and helping me understand this problem. Thanks a bunch!

So what happens if it's negative, for x-1 and x-3? How would I do it now?

Positive?

But how do I check if my x in x+2, x-1, x-3 is positive or negative? And could you give an example of how it would be if the domain was slightly different? Apologies if I may be annoying you with too many questions, but I want to truly understand.

So, because we need to take the given interval into consideration, we take the absolute value of each term? So that would be the final "simplification" and not x+4?

So the solution is going to be |3x-2|? Sorry if I'm not getting this, but could you please do it step by step, I'm really bad at this.
