Can you solve this Hong Kong elementary school math problem? I wasted about
20 minutes and gave up. No fair looking at the answer.-Bill

87 (less than five seconds)
I don't consider that math.
I didn't get it.
I sent it to my innately smart 23 yr old daughter, we'll see!

Here's one to waste time on,
I answered it, but not as fast as my innately smart 23 yr old daughter :-) I had to trash my first piece of paper, and start again. I think Einstein was wrong, more than 2% could answer it. Maybe 2-1/2% ;-)
Spaces 86 and 90 should have given it away. You must be thinking too hard. It is for first graders afterall.
My daughter emailed back,
"Well you must a raised a genius cause I got it. And it was before I scrolled down :)"
Don't know, it's a first grade math test!

10 seconds, but I had some wine. Those Hong Kong kids probably didn't get wine.

**Falsely calling it a math question is what confounds adults.
Call it what it really is - ie an "optical illusion" and most would solve it in less than 20 seconds.
Presented on a piece of paper without the highly misleading description would also render it obvious, especially to youngsters who have never tackled find the missing number questions before.

Saw it right away. Probably anyone who's done PCB layout will see it right off.

It is actually misleading to call it a maths question - it is much more of a pattern matching/intelligence question than a maths problem.
This one is a maths series problem although more for senior high school.
What is the next entry in the following sequence of numbers?
10 11 12 13 14 20 22 31 ....Again you either see it immediately or you don't.

If you had it on paper, you might think to flip it around. It is hard to rotate my monitor. ;-)
In any event, that isn't a math problem. No more than writing "hell" on a calculator.
-- Congratulations! You've now proven that you can compete head-to-head with Chinese pre first-graders. That **is** a surprise! BTW, 87 is wrong; it should be 128.
-- 34?
Something you can only aspire to.
It's so nice of you to prove my point.
I just saw that the characters were intentionally shaped to be readable from either direction. That's not common.
That made me go "Son Of A Bitch" once I figured it out. And I did not look.
-- Don't you even want to know why you were wrong?
First ten seconds spent thinking about 16,06, etc, then for unknown reason, the computer removes the image [goes blank] and starts over, as the image was laid back in that's when the dyslexic/chaotic mind took over and saw it instantly.
Shows all these great principles.
Thanks for posting that one!
I know you're wrong (always). I don't have to decode your utter nonsense (ever).
-- Well, then, I guess you know why "128" couldn't possibly be the right answer, so why don't you explain why I'm wrong, objectively, instead of just spewing your usual abject absurdities? Perhaps because you'd rather be known as a blowhard than as reasoning challenged, yes? John Fields
I gave it to my two kids with a "you'd better get this in 5 seconds or less" warning.
Daughter replied "that's not a math problem, that's a common sense problem."
Son did the math, got the right answer (not sure how), still in 5 seconds - and never realized what it really was a picture of.
Go figure.
