[Apokalipse]

2123?

That works if 567 is 57, but I'm not quite sure why it's 567.

I've got a stupid one that I heard the other day...

What happened on November 27, 2003 that will never, ever happen again?

correct!
lol, I didn't realise I put 567....

aª-b²=ab-b²

a^a doesn't necessarily equal a*b....

 

[Apokalipse]

a^a doesn't necessarily equal a*b....

she's right
the first line says a=b
it works if they equal 1 or 2, but not if they equal anything else
1^1=1
1*1=1

2^2=4
2*2=4

3^3=27
3*3=9

 

[Emily]

Here's one...

What line comes next?

1
11
21
1211
111221

 

[Apokalipse]

ummmm......
I'll give it a shot
adding up the numbers I get this:
1, 2, 3, 5, 8
.............can't see a pattern there

 

[Apokalipse]
