Math equation: Find x.

Next weekend AREA is taking the PSAT test for the first time, more as a practice test than anything else. Here is a figure to wish her good luck! And yes, I would think the answer is very creative and correct, but I bet the graders disagree. What do you think, AREA?

Wait, this is a trick question right? Because I can SEE the "x" right where someone circled it.

Maybe the x is only invisible to high schoolers? :)

This just shows how we percieve things differently based on how we are trained. I showed this to LA and he immediately figured out that x=5, and he didn't even see the circle and 'here it is' until I pointed it out (which lead to a large laugh!). We often don't see what we are not looking for.

About perception, it applies to kinds of humor, no? I think this diagram is really funny, and my comment(of course) I think is funny too. But others (LS included)don't even get it.

Differences in perception certainly applies to humor too ! :)

As a teacher, I would give full credit for this answer (possibly extra credit).
