Cause you may be given an interesting operation(not the standard addition or multiplication), and so might have to show closure

Definition of Group. Notice that they haven't used closure as one of its axiom because they have already mentioned binary operation. So no need to use closure as one of its axiom.

Every definition of a group in abstract algebra books that I have come across mentions closure as one of its axioms.

However, if you have already specified that the operation is a binary operation on (G), then there is no need to list closure separately as an axiom, because a binary operation on (G) is, by definition, closed.

LOL, my account wasn’t working as it should. Someone or some bot might have hacked into it. Everything is fine now, though. Sorry for the inconvenience!

You're right. But when told to show that a given set is actually a group, at least from my coursework, we were required to show that

As we all know
12 sides in a cube
...............
Size of one side of small cube = 2 m
Perimeter of smaller one = 12×2 = 24 m
...............
Size of one side of bigger one cube = 4m
Perimeter of bigger one = 12×4 = 48 m
................
Hence perimeter of both = 24+48 = 64 m
................
................
If options contain 62 m
Then according to figure
62 will be correct

Hey, I’m testing a small idea and could use your help 😅

Most of us save useful posts, screenshots, recipes, study tips, creative ideas, etc. from Instagram, YouTube, or other apps, but a lot of them just stay saved and never get tried.

If you have anything saved that you once thought, “I should actually try this,” just send me one screenshot or link.

I’ll turn it into a simple, doable challenge for you — what to do, roughly how long it should take, and when you could try it.

There’s nothing to install or pay for. I’m just testing whether this idea is genuinely useful in real life.

If you’re up for it, send me one saved screenshot/link 👀
