not just guessing the number 81, 72, 63, 54, 45, 36, 27, 18 or 9
OMG!!!!!!!
Oh my Gosh . He did...How?
I'm interested!
hi ,
any nubmer divided by 9 is going to end up as the result
Look, if you take a number N=10xa+b, where b is between 0 and 9 and a between 1 and 9. Ok?
So, you have (10a+b) - (a+b)=9a, right ? After that, look at the multiples of 9, they have all the same sign. When you have your result (ex: 12>1+2=3>12-3=9), which is a multiple of 9. The squirrel must just say these sign and he's right ! Understood, now ?
Oh... I can't understand.... I'm very sorry....
OMG! How?
Woof4, look, if you take N=10a+b, where b is between 0 and 9, and a between 1and 9, you have :
(10a+b) - (a+b) = 9a. Ok? So, the result can only be a multiple of 9 : 9,18, 27, 36, 45, 54, 63, 72, 81, 90. After that, look at the signs in the table. You can notice that all the multiplies of 9 have the same sign. The squirrel has just to show this sign and he's right. You see, it's no magic, but mathematics.
He's not a squirrel, he's a raccon!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I'ts an interesting game
Omg!! This squirrel is so smart!
It can see you in the camera and hear you if you move out of the way it gets it wrong I tried that and he got it wrong
Hi Haider7427. Let me reassure you that our games 100% do not use the camera or microphone. If we ever add a game that does, the game will say so clearly. Thanks for your comment :)

How did he do that??????Amazing...
TELL ME HOW THEN !!
It's a good game but it is very easy to understand how he knows the number :)
Oh, I got it. This game is just waste of time...
I am going to be mad! How!?
Oh, it is simple algebra: always the symbol from the card is following that numbers: 9, 18, 27, 36, 45, 54, 63, 72, 81... But this squirrel is clever, realy! :)
HOW, HOW he do it?!?
Sometimes he is wrong,but,yes,he is right in most time,so wonderful!
hi everbady
if add two numbers together and subtract this new number with old number - number ''9''!

Hi hannaramm57,
Thanks for letting us know. Is it loading for you now ? I've just tested it and it's working fine for me. Are you using Chrome, Internet Explorer, Safari or another browser? Perhaps you could try using a different browser and see it that works.
Let us know how you get on ...

Hi Sarahappy,
I'm sorry it's not working for you ... I've just tried it again and it's working fine for me. Take a look at my comment above which will give you some ideas to try out. I hope you manage to get it working.
Best wishes, Tina (LearnEnglish Teen Team)
I don't understand. It's too difficult.
