I don't get it. Is it supposed to be funny, please explain someone.

hey!! see tat 1st one... reflecton abt x-axis then x'll be -1,0,0,1
then AX=X... got it??
n d sec one... scaling by 2.. so A is 1,0,0,1..
so.. AX=X

The reflection one doesn't do much for me, but the other two are good.

@Tiffany
In the second the result would be 2x, but instead there is a big X meaning double.
In the third you project the letter 'x' in the y-axis and got the result. It is even draw the 'x' in the 'xy' plane bellow the third cartoon.
The first is the same as third but you reflex the letter 'x' in the x-axis.
:)

U should not have put the "hint" in the lower right... Your readers are not stupid morons!

Dude you can't say that you understand all of these comics. One comic may seem basic to you but other readers might not get it

Sorry Knusper, didn't mean to offend you :-(

I actually think it would've been funnier if it would have been big and in the first panel. Kind of like math homework where a student is misinterpreting the question. Like the ol' Find x. "I found it!"--->x.

Correction; not ALL his readers are stupid morons.

I reserve the right to be bloody moronic :D

I honestly didn't even notice the axis underneath until 'Knusper' commented about it.

@Umklapp
I think too!

I found the axis long after i read the panels and it got funnier! Hehe!

Haha, the hint actually makes it even funnier ...

how about a rotation ? ( (sqrt(2),sqrt(2)) , (-sqrt(2),sqrt(2)) )*x = +

I still can't get it even with the hint below...

Rotation by π/2

isn't the first panel actually a reflection about the y axis?

No; the y coordinate changes sign.
