I noticed that your school is Notre Dame College. What's that about?

'Notre Dame' is originally from French and when translated to English, it means "Our Lady". It is a reference to Mary, the mother of Jesus. The school [or college as it is called here] was founded by the Congregation of the Holy Cross.

The school is very strict about discipline and attendance is 100% compulsory. This part is from Wikipedia:

Notre Dame College gained reputation of the best institution for higher secondary education in the country. The highest number of perfect GPA holders in national examination (H.S.C.) and the exceptional success of its students in university admission tests bear testimony to this.

On the downside, they put too much pressure on you and there's a ton of homework everyday. The school website always seems to be unavailable.

Ah, I was thinking of that you got into Notre Dame in US. Didn't know that "Notre Dame" meant "My Lady", and that there are several higher education institutions with Notre Dame in their name.

Time to revisit Duolingo to learn French :)

@Fahim Shahriar Shakkhor , nice job being the only person to finish "I Don't Have A Name For This Yet!". Did you like the problems? Which one seemed the hardest to you?

Mursalin Habib - 3 years, 8 months ago

Pie? and Answer Very Carefully! bothered me much.

I assumed \(\pi+e\) to be rational and I almost forgot \(0\) is rational. They were really good ones.

@Sharky Kesa , how did the AMC go? Do you have a favorite problem?

Mursalin Habib - 3 years, 4 months ago

Log in to reply

I was doing the Australian Maths Competition, not the American Maths Competition. It was way easier than I thought it would be. My favourite question probably was the last question.

What is largest 3 digit number such that it is equal to the sum of its hundreds digit, the square of its tens digit and the cube of the units digit?

I am pretty sure I was the only boy in the classroom to get that question (we had female teachers who also did the test as a practice of their skill).

Victor Loh was also participating in this so you can ask him as well.

Sharky Kesa - 3 years, 4 months ago

How did you approach the problem?

If you look at it, there aren't many cases to consider. Even a brute force approach shouldn't take much time.

Mursalin Habib - 3 years, 4 months ago

Log in to reply

@Mursalin Habib Hmm, yes. I first eliminated the cases for the first digit and last digit. This greatly reduced the number. Then, because I didn't want to get it wrong, I used trial and error to determine the answer.

@Rubayet Tusher , congratulations on leveling up in algebra! I see that you are maintaining your streak for the last couple of days. Why don't you post a problem so that others can give it a shot? And you should seriously consider following some more people.

@Trevor B. Here's your favorite joke with a new twist.

There are 10 types of people in this world.

1) Those who don't know binary.

2) Those who expected the 10 to be in binary.

3) Those who expected the 10 to be in ternary.

4) Those who expected the 10 to be in quaternary.

5) Those who expected the 10 to be in quinary.

6) Those who expected the 10 to be in senary.

7) Those who expected the 10 to be in septenary.

8) Those who expected the 10 to be in octal.

9) Those who expected the 10 to be in nonary.

10) Normal people.

[This joke assumes that normal people know binary and there is no intersection between 1 and 10 :)]

Here's a trick question that I came up with myself.

What is \(1+1?\) Base \(10,\) no tricks! \(10,\) because the entire question was in base \(2.\)

I was actually going through people's profiles and read that this was your favorite math joke.

@Mursalin Habib Oh, really? I need to update that then. It's been a really long time since I took a look at that. I'm curious - did you have the willpower to read my entire post on the beauty of mathematics?

Trevor B. - 3 years, 8 months ago

Log in to reply

@Trevor B. I loved reading it. I like reading other people's profiles when I'm bored.

When was the last time you updated your profile? Because I'm pretty sure there was some mention of Bob Krueger there somewhere [just curious, that's all].

Mursalin Habib - 3 years, 8 months ago

@Mursalin Habib I think I updated it about two or three months ago.

When I was doing my science fair project, I needed to learn relatively advanced Python in a week, so I asked for some help with the code. He provided a sample code that I used in the project to get second at the county science fair, and I made a mental promise to pay him back by learning Python. The rest is history.

HAHAHAHAHA! Yes... It's quite hard to do! You click on one person, then you click on another, then you click on another, etc.. It's MUCH harder than being followed by 3000 people! Totally... (sarcastic face). :D

Thanks!

This is so embarrassing. This is what I got.

@Mursalin Habib Is there any hope of another MCQ set like the "Not As Easy As [1], [2], [3]" set? I really enjoyed it.

Justin Wong - 3 years, 5 months ago

I don't see why not.

However at this exact moment I do not have enough ideas for an entire set. Give it a week.

I'm really glad that you enjoyed the sets.

@Blake Mitchell , welcome to Brilliant! You should consider following some more people if you want more things in your feed. The search bar is a great way to find a lot of great problems and notes. If you search for "." [the period symbol], you practically pull up everything. Then you can use different filters for problems, sets, topics and levels of difficulties. Enjoy!

@Abba F , welcome to Brilliant! If you're looking for problems of a specific level, use the search bar. Search for "." [the period symbol] and filter topics, tags and levels. You should also consider following more people if you want to see more stuff appear in your feed. Have you seen this?

@Mursalin Habib It says in your profile that you like reading webcomics. My favorite is Homestuck, by Andrew Hussie, and I have included characters from it in a couple of problems (like this one) off of it. Have you heard of it?

Trevor B. - 3 years, 8 months ago

Log in to reply

I haven't heard of it, sorry. I'll be sure to check it out!

I like xkcd, spikedmath, abstrusegoose, zenpencils and cyanide and happiness to name a few.

Mursalin Habib - 3 years, 8 months ago

Log in to reply

Ah, I enjoy Cyanide and Happiness as well.

If you want to check out Homestuck, you should probably know that it is really long (almost 6000 pages and counting). It seems really pointless at the beginning, but everything in the beginning will make sense later on. And lastly, know that when you get past all of the weird stuff that happens in it, there lies a really interesting commentary under the surface. Basically, if you're patient enough to read it and you don't mind reading about some really weird characters and events, the hours you spend reading it will be well worth it when you finish.

But if you don't like it, that's fine. Lots of people can't get over the fact that the first 500 pages or so (the pages are really short, sometimes) can basically be summarized by "No one can find any of their belongings."

I hope you like it!

@Peter Taylor , do I qualify as a person who's worthy of being featured i your "cool people's message boards!" set? :)

By the way, although people can't directly re-share this note, there is a way to re-share this. If you like it, it goes to your "liked" feed and it is re-shareable from there. Are there any plans to fix this [It's really not that important but I'm just putting it out there.]?

Mursalin Habib - 3 years, 8 months ago

Log in to reply

It was so woefully incomplete without you :)

Let me know if other cool people are making message boards, and I'll add them.

Re: the "hacky reshareability of notes published directly to sets" I will add it to our cue of bugs/minor inconsistencies. We will fix it when all other things of higher priority have been fixed(which could be a very long time). E.g. when ever presented with decisions about how to spend our time like "make the website faster" or "block resharing of notes that were published directly to sets" we are always going to go for things that affect more people. Thanks for bringing it up though!

@Tahsin Ahmed You said that you are not a big fan of the MCQ system. Did you try out this set of problems? These problems wouldn't work without the MCQ format and the solutions require proving something as opposed to finding a numerical answer. Let me know what you think of them.
