IMO combinatorics? and china?

[@invincible9240]

Amazing initiative ,please continue this series

[@ShefsofProblemSolving]

Will do!

[@mrlegend3983]

Thanks for the initiative

[@emmanuellaeledu]

Thank you so very much, Sir!

[@ShefsofProblemSolving]

You are very welcome

Please also algebra💪 Love this “series”

[@ShefsofProblemSolving]

So algebra is the one I haven't filmed thus far because I haven't figured out how to structure it yet. There are functional equations, sequences, inequalities. Those are the well known. Now it's hard for me to recommend books because I've never come across an algebra book and I learned it mostly through problems and handouts. Anyways, difficult to structure, if you have any ideas let me know, but right now I'm in the thinking process.

[@maxicambo4017]

@@ShefsofProblemSolving yeah exactly, algebra is the only one you dont have books and stuff for. Also which handouts did you use? Thanks in advance And also what is your favorite subject considering NT, algebra, geo, combo

[@ShefsofProblemSolving]

@@maxicambo4017 Honestly forgot most of the handouts and they are in my native language, so it's not useful to share those. I'll look into this and see if I can come up with some handouts. Difficult to say! I really liked Geo, because adding a point sometimes and solving a problem is beautiful. Combinatorics is wider and more mysterious and I guess that's why I'd choose that as my favorite.

@@ShefsofProblemSolving thanks for information! Yeah mine is combo as well

[@shauryabhardwaj9643]

@@ShefsofProblemSolving Please look into Inequalities by B.J. Venkatachala and Functional Equations by B.J. Venkatachala...2 really great books...

[@drozfarnyline4940]

Hi Can you please give me the source of the quote about Mathematical Induction. I really love it.I have been doing induction since last week and suddenly induction makes a lot sense to me Thanks in advance

[@ShefsofProblemSolving]

Thank you for the kind words! Actually I don't have a source it's just something my coach used to say in lectures on induction

Now how to get better at geometry?

[@Miguel-xd7xp]

Pray to Evan Chen, jokes asides EGMO (euclidean geometry in math olympiad) is like the best book currently for geometry imo :)

[@ShefsofProblemSolving]

@@Miguel-xd7xp Praying to Evan Chen isn't an option I would write off too quickly... Video coming out Sunday!

[@someperson9052]

You kind of sound like Stephan Hawkins' computer voice

[@ShefsofProblemSolving]

HAHA This made me chuckle ... I've never been told that, thank you for making my morning :D

Hi good,

[@ShefsofProblemSolving]

Thank you :)

stopped listening after hearing i need to solve problems lmao (jk jk)

Why don't you write proofs clearly? I know you are a great mathematician with undoubtedly impressive problem solving skills, but if you do not write these proofs down, what'd you think how we will ever comprehend what you tell us about. Also, considering that you do not have many views on KZbin, maybe you should change the way you teach us, not just nonstop talking. Micheal Penn is definitely no less great mind than you and even better, he's a professor, his proofs are very creative to understand
