63 - 6 - 3 = 54 okay I just figured it out. Everytime you try it, it associates a different symbol to the multiple of 9.

so if you use the above example 63-9 = 54 and look at 54 then click the box you get a different symbol each time, and all the multiples of 9 have the same changed symbol.

Pretty sneaky for about 5 minutes

That's a shit hot trick.

It was spoilt a bit, as it seemed to get it wrong at first. Reason was that (being a stupid fuckwit) I was looking at the symbol to the left of the number rather to the right of it.

i don't get it, it can't get mine right.

I'm unreadable.

Must be because I back clicked and it didn't change the images on reload. Because it's impossible for it to get it wrong now that we know the trick.

I'm worried about you guys whose minds it is not reading right 100% of the time.

You guys need to work on your subtraction :)

Porn wiz kids good job. I'm pretty good with math, but I didn't catch that till you pointed it out. Going to throw this on my Russian programmer and see if he figures it out instantly. Which he should cause he went to college at 13 and graduated with masters in applied mathematics and computer engineering at age 17. This should be interesting.

actually that is correct took me a couple minutes to figure it out but looks like you got here first now the interesting this is to go through and find how many people say it go theirs wrong an you will know who can not so subtraction. :)
