MAt what ages can kids use Fitbrain ?

Ariel NiuHi Michelle, we have an app just for kids ages 2-8! Check it out: http://taps.io/fitbrainskids

Chahehe Amazing

devikan03i wanted some questiong which are relevent for grade 7 can i get some suggested website

lewayYour equation, (6-3)×11-9=24 is written wrong. The “×” adds a variable and becomes incomplete. Then becomes x=7.3333. It should have been written; 11(6-3)-9=24.

Michael Cole@leway, the “x” is meant as a multiplication sign.

PeaceThis is pretty cool…

MattAgiusCould also be (6+11-9)•3

Tim BusseI had a different calculation with the same outcome. 3*(11-6)+9=24

nathanyaFriday Mystery was pretty complicated but…..cool

ChrisI wouldn’t use the word mix in the emperor last chance marbles puzzle, sounds like mixing the contents between bowls. Swap would be better.

Also, it doesn’t state that the daughter is the youngest in the family mystery, surely that shouldn’t be assumed?

Great puzzles!

Mark(11-3)(9-6) is an alternative solution

AeivuhThese are cool

On the one with finding how to get 24, there is more than one way

KoreWhen people are trying to sound smart but are saying something dumb. @leway

sthe parenthesis already show multiplication

JoshuaHard stuff

TananiaI never knew there were so many questions that could be this hard. To be honest, I answered 2/all of them correct. #reallyhardstuff

TananiaAnd I’m ten years old!!!

shaheen maroofWow its ……….. i salute this😆😆😆😆😆😆😆😇😇😇😇😇😇😇

PeggyIn the second murder mystery, we have to assume Dan is still alive. But why? We know only that he ran in the marathon yesterday, not that he is still alive today. Perhaps the time of the murder shod be given. Only then could we conclude that Dan was alive.

Also, the marbles solution gives you a slightly less than 50% chance of winning. If he mixed the bowls up evenly, his chances would remain firm at 50%.

LillyIt should be * instead of x @Leway

SHIVLINGAwsome……..

RyloreBEDMAS. Anybody remember that? It’s why McDonalds and other companies have wrong answers to “skill testing” questions. Whatever idiot they had write up their questions obviously forgot about BEDMAS and tried doing their equations left to write one number at a time. It will give you the wrong answer EVERY time!!! BEDMAS = Brackets, exponents, division, multiplication, adding, subtraction. That is the correct formula for determining the answer to such questions, which apparently Leway wasn’t aware of. It is also the reason why McDonalds had to award two prizes: they gave the prize to someone with the WRONG answer (because that was the answer they were erroneously looking for) and had to give the prize out again to the person with the right answer who had to bring in a mathematician to explain to McDonalds how mathematics works. If companies are going to issue aptitude tests, they might want to make sure the idiot they hire to make them up actually has an ounce of aptitude him/herself.

TriciaThese stink!!!😄😘😡😠😤👿

Leya SladeFunny need more stuff like the last one and the relationship ones

TonyTheae are flipping kool yo. I definitly not forgetting anuthing here.

I AM AWESOMEThis is hard

jennyit could be[ (11 – 6) 3 ] + 9 = 24

E@chris It’s not assumed, through hint 3,4,6 it’s determined that the youngest in the family is the witness, and hint 2 says that the oldest and the witness were not of the same sex, and hint 5 says the oldest in the family is the father which is male, so the youngest in the family must be female, and since the mother can’t be the youngest, so the daughter must the youngest.

Hope this helps

Mike C@Peggy, on the marble question – if you split them evenly, it is 50/50. If you put one marble in the one bowl, and the rest of them in the other bowl, you have a 74.5% chance of getting white. That is because your chance of getting either bowl is 50-50, so 50% of the time you get a bowl that is 100% white, and the other 50% of the time you get a bowl that is 49% white (49/99). so 50% all white, 50% mixed bowl which breaks out as 25.5% black and 24.5% white. So in total 74.5% white mixed that way.

SreshthaIt is too hard”……..easier next time by Sreshtha

ILOVESOCCERPRETTY HARD I GUESS.

BUT WHERE CAN I DO MORE???????
