Just because they have gifts, doesn't mean they aren't autistic.

Ooh there's still this which I had forgotten about, still very worth mulling over it hmm :thinking::slight_smile:

And ooh I know only about some of the xckd comics (which can be funny and thought-provoking although also I think some are more inappropriate) but I like the part of them making things accessible in nice doses. Does this book run similar to that? :smiley: (Hehe I'm not quite up for a bit more attention heavy content at the moment, just casual browses :upside_down:)

minor frustrations with this problem

First instinct was "oh, this is 10!, that's easy!" but of course,, i go to check it and, welp,, 10! is 3,628,800, not 3,628,200. So that's out.

I'm going to go hunt for factors here and see... I think a square root may be involved?? idk


#201

Oh, I've heard of the book. It's a book full of random questions, and then extremely methodical and scientifical answers to those random questions. It makes for a fun read, although I prefer to take it a single chapter at a time, to avoid brain overload and to make sure at least some of the forumlas and infrmation is absorbed.


#203

Yeah, the book doesn't have the raunchiness in it

(I was quiet sad when I figured out the online did have it though, because I was excited to tell my parents about this new science resource. Little did I know about xkcd at that point and my parents told me not to use the site)


#206

They are, but they're not nice. There are kids in this forum and I don't want others cussing in front of the kids. This is one of the dangers of social media. sigh.


#208

This is a cool topic. I like math! Right now in school it's not fun because we got a good teacher and I already know pretty much about the subject.


#209

Yeah, that's a bummer. Would you like a math problem to think about?


#210

Ok, I'm probably gonna post a math problem here that my grandpa told me a while ago. (I forget it now but I'm gonna call him and ask) it's pretty easy I think but taking a long time to make.


#211

Cool!

Here's mine

if x is even and less than ten
And y is odd, but greater than 5 and less than x
What is x*y?

I have another one I'll edit in

If a square is inscribed in a circle with a diameter of 5, what is the area of the circle, subtracted by the square? (Sorry, this doesn't give a nice solution)


#212

Your: I think there's many answers: x= 9/8/7 y=6/7/8
So it could be 6*9= 54, 6*8= 48, 6*7= 42, 7*8= 56, 8*9=72


#213

I don't know the other one. I don't know how to count it out. I'm not that good at math yet​:sweat_smile: I have to practice


#214

X must be even and y must be odd. So, x can't be 9 or 7.
Good try, though


#215

Oh, I didn't think about that. I'll post a really hard math problem here sometime. I'll try to make it by myself first.


#216

Oh wait, if was pretty easy. I didn't though about that y was odd and I didn't know what even is. I'm swede​:sweat_smile:


#217

Oooh woah that's really close!! that seemed like such a good fit though hehe.

I gotta go but thanks @XiaoMiaoMi and @JonnyGamer for telling me more about the xkcd book :smiley:


#218

I think that the answer to the first one is 56, x=8 and y=7

Erm I'm not so sure about the second one.


#219

Nice you got it right!
Yes, the second one is a though one. It will all make sense when you do Geometry and learn about pi (it's actually really interesting!).

Also, I'm sorry about @ihaveexpectations, that was a really nasty issue


#220

so 5 would be (x being square side length) xroot2.... yep this doesn't seem very friendly already


#221

For the second one, I have a guess? 15.421230825151625 It's probably not right. I can't think straight because my Gifted teacher is retiring and she was a good teacher.
