Hello... I am currently a newbie in mathematical competitions... It's my first time joining mathematical Olympiads, not to mention, starting from Philippine Mathematical Olympiad this year. I have some questions regarding these contests:

1. In number theory, can I use the laws of algebra or (other branches of mathematics I know) in this matter? Just to ensure knowledge.

2. How much do I need to know mathematics (apart from the mathematics subjects offered in my school and that I parallel study or independent study) in order to succeed in the contest? The subject is very new to me, yet I know some of the concepts yet I don't master some.

3. In mental competition, how does one achieve answer especially questions are difficult when mentally calculated? (Actually, I don't have much experience with mental calculations, except for MTAP orals.)

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

• Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
• Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
• Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.

If it's your first time I'd say don't worry about it too much. Just go in with what you know already and see how you do. The more you do these things, the more theorems you get introduced to, the more tricks you learn, and ultimately you get better at problem solving. If it's your first time then, hey, no pressure. Just try your best and see what happens. And, most importantly, have fun with it. Don't do math for a chore, please. If math ever feels that it's tedious and not worth your time, then take a break.

Thanks.. but I'm having a bit of trouble in number theory and algebra.... I found finding training too short because I have school for almost a day (at most 12 hrs.).. Any advice here?

well said!

hello, did you start your review already? :))) It is my first time too to join the Philippine Mathematical Olympiad this year.

I hear there's a cool new contest called Proofathon coming out soon... ;)

Indeed. I am very excited about the inaugural contest, which, according to the home page, will be held on $26-27^{th}$ October. What's most exciting is that the contests are focused on specific subjects, which vary across the year.

that's nice :)

For those who have first time joining math olympiads (especially PhMO and others), I recommend you to read Mathematical Excursions, written by Dr.Ian June Garces. This book is a pre-olympiad introduction, starting from the fresh concepts of algebra, number theory, geometry and combinatorics up to some challenging IMO-caliber problems.
