Basic Number Theory - What are Relatively Prime Numbers?

The following is my covering of the following topics:
-Relatively Prime (n is prime to m)
-Prime Numbers (in general why 1 is not a prime number)
-Greatest Common Divisor
-Euclidean Division Algorithm

-Enjoy and have any questions do ask :)

Have a beautiful day!

Just want to say that you are very smart in your topics and you are well knowledgeable and all but can you please and pretty please use simple thinking strategy and easy simple steps to share your knowledge. You have too much lighting on the board that your examples don't even show up. There are a whole bunch of us out here who are visual learners so we need the visuals.

@KCAASE Yes I highly apologize for the lighting of this video. My more recent videos typically have better quality lighting. I'm not quite sure what you mean by "simple steps". Thank you for the input :). I'll keep your suggestions in mind in my future videos.

at what math level do you need to be if you want to learn number theory?

[Entertainmentwf]

Number Theory is very appealing since it is very broad in it's studies. You can learn some concepts even at a middle school or high school level. For example Pythagorean triples are taught to most students in mid-middle school in the form of Pythagorean Theorem. Typically Number Theory is quite difficult if you really want to get into it which is typically offered at the University level. Number Theory offers a lot of variation of difficulty. I hope that helps :D. Proofs are important in it.

If you want a good book on Number Theory I highly recommend "Elementary Number Theory", Underwood Dudley. It runs through all the fun stuff and makes it pretty well sensed. :) Number Theory is awesome because, it gives you a vast toolbox of neat properties, proof techniques and even formulas for things that people would doubt would have any pattern unless they studied the stuff. :)

Short answer: Just be comfortable with proofs and discrete mathematics. Some of number theory is very simple to approach but, has trickier discrete proofs, while others have very complicated topics. Overall you see hints of principle of mathematical induction on the odd time aside, lots of clever proofs. Definitely very useful properties and relationships can be found :).

LOL. I tried my best. I hate that stupid light in my room and it's spotlight action lol. If it wasn't there you'd be able to read it. That's why I included the text lol. ha ha. You are so sweet :).

Dan.....you know I admire you but I can't see the board...0_o I wanna see the writing on the white board! ME LIKE WHITE BOARD! XD
