Did yall really expect me to actually get that??? Im sleep

Dang! I tried explaining the same thing to my group when we were doing this and none of them understood what I meant.

Except your relatives would still see you got all of the inheritance and pester you for life?

• September 17, 2017 at 2:50 am

My way is kill the others and say the fought for the money

• September 17, 2017 at 2:50 am

They can still pester you about the money, even if you won it fair and square.

Am I the only who actually tried to solve this ? I'm only half way, tho.

• September 17, 2017 at 2:50 am

OMG =.= Math . I think I don't like it =.=

The uncle could've just told her the code…. The relatives would've pestered her no matter what…

I started charting this out in Excel and quickly noticed the tendency towards square numbers, but I couldn't name the particular reason why – this video did a good job of explaining that.

10 second for know
10 minute for do

This reminds me of the 39 clues first book series.

• September 17, 2017 at 2:50 am

OR your uncle could just tell you the answer before he died.

• September 17, 2017 at 2:50 am

This reminds me of The Westing Game

what about 30? 30 has odd number of factors

• September 17, 2017 at 2:50 am

I can resolve this and I am glad for that!

uncle, instead of making this riddles, just give her 99% of your inheritance secretly by sending it to her bank account. and then ask the one who read you will to say "I give my inheritance to everyone equally." but its only 1% of em. pfft..

I would like to do this riddle but the animation contradicts itself, the second key doesn't change the first locker, yet the third key does.. (1111->1010->0001)?According to how this scenario is worded the first three state changes of the first four lockers should either be (1111->0101->1100) or (1111->1010->1000). If the animation is correct then why isn't it clearly stated that even numbers begin at 0 and odd numbers begin at 1? It would have to alternate between the two for the animation to make sense at all. I just watched the solution and it says that 3 remains open yet in the explanation animation it clearly gets closed LOL. I didn't even attempt this because of that.

So your eccentric uncle is banking on the fact that you binge-watch Ted-ed's riddles.

• September 17, 2017 at 2:50 am

Yeah about that I'm not smart

• September 17, 2017 at 2:50 am

Who is watching at the 3000's??? Don't like my comment .3.

• September 17, 2017 at 2:50 am

Who else watches these videos just for the story and cute animations?

• September 17, 2017 at 2:50 am

I think if he gave it to me the relatives would just treat me as their master for the money XD
