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.

Can anyone argue with me on the value of $0^0$

- 8 months, 3 weeks ago

I will like to see your opinions on the value...

indeterminable is not an accepted value...

- 8 months, 3 weeks ago

It's either $1, 0$ or undefined according to what field of mathematics - BRILLIANT has posted a video about this on Youtube...

Also, this is not my opinion, this is BRILLIANT's video's opinion...

- 8 months, 3 weeks ago

And may I have your opinion, with a good understandable proof, please?

- 8 months, 3 weeks ago

My opinion is in alignment with BRILLIANT's video's opinion:

- 8 months, 3 weeks ago

So...

Any home made proofs on $0^0$ 's value?

- 8 months, 3 weeks ago

No, because I'm impartial to $0^0$'s value.

- 8 months, 3 weeks ago

please, in the love of lord, do not ban emoticons

slang can be banned, but not those...

examples of emoticons are: (!), =D, XD, :)

- 8 months, 3 weeks ago

Uh.....................................................................................................................................

- 8 months, 3 weeks ago

You have been given exception $1$ for using the i dont know what to say emoticon

this is the reason for the ban

.....................................................................................................................................

For a good excuse that you can make, comment back on this thread

- 8 months, 3 weeks ago

Good one. But I made the rules. Also, all the dots are actually elipses.

- 8 months, 3 weeks ago

Exactly!

But when I send this emoticon...

$=D$ | =D

You do not agree that the emoticon means "equal to $D$" (whatever D is...)

P.S.

This is a joke @Yajat Shamji

I repeat, this is a joke (though i dont think it is a good one)

- 8 months, 3 weeks ago

Good joke.

P.S. Can you teach me emoticons?

- 8 months, 3 weeks ago

Just post your feeling on letters

=D means you are happy, as when you turn your head till you notice the D as a smile, you get a smiley face!

- 8 months, 3 weeks ago

Oh. Also, did you re-read Rule $1$?

- 8 months, 3 weeks ago

(゜O゜)

Thanks!

- 8 months, 3 weeks ago

No problem - although don't use it all the time.

- 8 months, 3 weeks ago

I use it frequently.....

Though I am a lover of perfect English too...!

- 8 months, 3 weeks ago

Also, how is that an emoticon? The reason why I banned them in the first report room is because I don't know about emoticons!

- 8 months, 3 weeks ago

Emoticons are a substitute for emojis as they are easy to copy, and easy to use

uugh!

In texting, we use the fancy way of...

.....................................................................................

- 8 months, 3 weeks ago

Can you show me all of them?

P.S Read the edited Rule $1$.

- 8 months, 3 weeks ago

No

No one can do, it is impossible

- 8 months, 3 weeks ago

Is there a database of emoticons?

- 8 months, 3 weeks ago

Maybe, maybe not

There is a collection of one though

- 8 months, 3 weeks ago

Can you give me a link or a website?

- 8 months, 3 weeks ago

https://upli.st/l/list-of-all-ascii-emoticons

The motherload of all ASCII emoticons

Spend some time on there @Yajat Shamji

You will spend a lot of time there

- 8 months, 3 weeks ago

I'll spend time tomorrow.

P.S. I found out about your joke as soon as you said exception - there is no exceptions (for now...)

- 8 months, 3 weeks ago

Er...this may be just a random thought, but I just found something about 512.

$51-2=49$

$12-5=7$ (look at it backwards)

$49=7^2$

Can you find more numbers like that?

- 8 months, 3 weeks ago

Rule $6$... @Sachetan Debray

- 8 months, 3 weeks ago

Er...this may be just a random thought, but I just found something about 512.

$51 - 2 = 49$

Looking at it backwards gives us

$12 - 5= 7$

$49 = 7^2$

Can you find more numbers like that?

..............

I don't understand this comment @Sachetan Debray

Do you @Yajat Shamji?

- 8 months, 3 weeks ago

I think what @Sachetan Debray is trying to say, find other numbers like $512$ that when the third digit is subtracted from the first two digits, it produces a square number and when the first digits is subtracted from the last two digits, it produces the square root of the third digit subtracted from the first two digits (i.e $x_2, x_3 - x_1 = (\surd (x_3 - x_1, x_2)^2$).

- 8 months, 3 weeks ago

Yeah, that's right. I tried to find more numbers like that, but it didn't work out. Its a weird thought that popped in my head last week. But I think there should be more such numbers.

- 8 months, 3 weeks ago

Okay. Tell you what, make a note on it and ask @Zakir Husain and @Mahdi Raza. @Sachetan Debray

- 8 months, 2 weeks ago

Sure

- 8 months, 2 weeks ago

Give me the link as well.

- 8 months, 2 weeks ago

Right. I'll combine one other weird idea I had and this one

- 8 months, 2 weeks ago

I like it, but please read Rule $6$, @Sachetan Debray

- 8 months, 3 weeks ago

Is it fine now or did I mess up again? Is this how its supposed to look?

- 8 months, 3 weeks ago

Oh, sorry @Sachetan Debray!

Do not add the inverted commas

They shouldn't be there, they should be excluded

- 8 months, 3 weeks ago

Did that make any difference?Is it ok now?

- 8 months, 3 weeks ago

👍🏾

- 8 months, 3 weeks ago

Looks great now

- 8 months, 3 weeks ago

Ok

- 8 months, 3 weeks ago

I'm sorry, I don't know what Latex is. Is it some sort of formatting tool? But I can't see it in the easy Math editor, although I can see it when I'm posting a problem of my own. Does it not work for comments or something?

- 8 months, 3 weeks ago

I got what it is. But I still can't find it in the formatting guide. @Yajat Shamji?

- 8 months, 3 weeks ago

I used the Math expression, but that is not Latex, as far as I can tell. Once you tell me what it is, I'll surely follow the rule. I didn't know I had to use it separately for Math, so I used the normal format.

- 8 months, 3 weeks ago

When we are to enclose numbers with "\ (" and "\ )", we are typing in latex

We should join the stuff enclosed with inverted commas

- 8 months, 3 weeks ago

Yes, it is a formatting tool

- 8 months, 3 weeks ago

Great, thanks!

- 8 months, 3 weeks ago

Hey @Yajat Shamji, I just wanted to give you an idea for a question

Refined Reflection Problems

Brilliant hasn't done well with that... On the math style

What I am trying to say is, if we were to give the centimeter measurements for the light box, and show them where the looking glass is, the question is possible without trial and error. We just have to ask the angle as the question

- 8 months, 3 weeks ago

Nice. Send me text and an animation (if possible). @Hamza Anushath

- 8 months, 3 weeks ago

Alright, and I'll try

But before that, I have to mention...

I will also make questions on this topic

I believe that this should be a universal topic...

- 8 months, 3 weeks ago

That's fine. After all, Rule $4$ is alive now...

- 8 months, 3 weeks ago

@Mahdi Raza, @Hamza Anushath, @Brilliant Mathematics, join in but first read the rules.

- 8 months, 3 weeks ago

Does anybody here want to join me in the search for Quadruple Mersenne Numbers? I have already found Triple Mersenne Numbers...

- 8 months, 3 weeks ago

Hello? Anybody there? @Hamza Anushath

- 8 months, 3 weeks ago

Hello? Anybody there? @Hamza Anushath

- 8 months, 3 weeks ago

@Hamza Anushath, take a look at my new avatar!

- 8 months, 2 weeks ago

@Yajat Shamji, I should say that it is pretty good!

- 8 months, 2 weeks ago

I like Euler's formula! That's why it's my avatar!

જાણે તમને ગુજરાતી ગમે છે. મેં હમણાં જ તેને અજમાવ્યો અને જુઓ કે તે કેવી રીતે જાય છે ...

શું મેં સારું કર્યું @Yajat Shamji? (હું ગુજરાતી નથી બોલતો ...)

- 8 months, 2 weeks ago

Made possible with a bit of net browsing skills =D

- 8 months, 2 weeks ago

Nice!
