Did he just ask about the haircut under his cap?😂😂😂

[brunoalsi]

Props to your barber, for making your hair looks exactly like a cap hat.

Andy I’m a national math Olympiad competitor in Brazil, and when I’m tired of all the complicated stuff and want to do some fun little problems you channel is perfect! Thanks :)

[starboy]

Thanks for not skipping the process of solving. This is why your Algebra is addictive like a movie.

[Forget_me_not_art]

I like watching your videos, when I feel stressed, thank u <3

[Topcatyo.]

I started following this channel a couple months ago and even though I am bad at math these videos make me enjoy it and feel like I could be good at it eventually.

[DeadCarrot]

Nice Haircut, also second time asking for AMC 10/12 practice questions. Love your vids

I don't exactly have pen and paper handy for most of these, but your solution was exactly what I imagined before I started! Almost. I was going to go into sin/cos/tan instead of the theorem. It was still very exciting! Even without using pen and paper, I've watched enough of your stuff to start planning solutions before I begin!

Hi andy, there is an organisation in uk called uk mathematical trust, the questions in the competitions are really fun ;)

[MichaelPlate]

I actually knew how to solve this. Seems like I'm learning thanks to your channel!

[dumbozo]

these videos are so cool! I love these

[jmsaltzman]

Time warp back decades to mathletes with this stuff, thanks Andy!

[sirllamaiii]

Where do you find all these challenges? Is there some repository of them all?

[Reskrox]

Hello Andy, you appeared on my feed like a year ago and I've found your shorts and videos really nice to follow along, you made math fun again for me, thank you

[OptimusPhillip]

I got pretty much the right numerical value, but I did a bunch of stuff with sin and cos that I probably shouldn't have bothered with

[hvnterblack]

New haircut? How exciting! By the way, sulution is nice too.

[jerrypolverino]

I love this problem and I didn’t use algebra to solve it. Although, admittedly, my procedure was a little convoluted.

move circle 4 up so radius aligns with circle 6, imagine moving circle 3 down to align with radius of circle 4. Now all the circles radius aligns horizontally, but circle 3 over laps into circle 4. You now have 3 + 2 + (2-1.5) = 5.5

Done with school years ago but still love math questions
