Try to resolve this games. Pm me the solution if you get it and then you will get a mod. For any hints write here.

1: Difficult: Easy

9+
68+
35+
43+
27+
84=
208 ??

It's really a strange solution. Infact there are 3 figures that must be eliminated for giving the indicated result.

I have resolve it in only 2 minuts or less.



2: Difficult: Medium

I'v got a Bunch of 10 cards. I put the first one to the end of the bunch. I take then the first card of the bunch , it's a 1. I put the first 2 card of the bunch to the end of this. I take then the first card of the bunch, it'a 2. The order of the exit of the card is 1-2-3-4-5-6-7-8-9-10. What was the begins order of the cards?

I have resolve it in 13/14 minuts.

3: Easy

The number of the plate of a car is composed from 5 figures, whose addition is 27. The first figure it's equal at the fifth, and the fourth is the their triple. The third one is the their quadruple. The addition of the first and the second is 17, What the number of this plate?

I have resolve it in 2/3 minuts or less


4: Easy+

35 12 6 35 4 =72

Try to put in the following series of numbers 2 symbols "+" and 2 "-" to let out the result 72.

Solved in 1/2 minuts


5: Easy/Medium

With use ten time 10, and the symbols +,-,x and :, try to get 100.

;)

6: Easy

Add the figures of N=(10 to seventh)-2007. What is N?

Ok, for number 2, this is the algorithm?:
Move 1 card from top to bottom, flip next card, its a 1. Remove the 1.
Move 2 of the remaining 9 from the top to the bottom, flip next card, its a 2. remove the 2.
Move 3 of the remaining 8 cards from the top to the bottom, flip next card, its a 3. remove the 3.
Move 4 of the remaining 7 cards from the top to the bottom, flip next card, its a 4. remove the 4.
...

If so, then the starting order was:

I saw a similar problem to number two, except the algorithm was:
1) Remove the top card.
2) Take the new top card and put it on the bottom.
3) Repeat until all the cards have been removed.

It has a very similar solution, but it gets really interesting when one starts with the cards in order and at the end, takes the new stack of cards and starts over. The question being how many times must someone do this before the stack of cards is in order again. Try to solve it for n cards. (I have not been able to do this.)

No, it's wrong. If the order was 9 1 8 5 2 4 7 6 3 10, the order of the exit of the first 3 card is 1-2-7! The correct order must are 1-2-3-4-5-6-7-8-9-10.
Infact, take 9 and put in the end of the bunch. Take the first card, 1. take 8-5 and then put it in the end of the bunch. Take a card, 2. Try now to put 4 in the end of the bunch, take a card. 7.

Not according to the algorithm clarification that I posted. If that's not the correct algorithm then correct it and/or clarify your original post. However, according to the process and order that I posted, here's what happens:

You need use all the symbols (+,-,x and : ) for the 5.

for the 2, every time you put 1 or 2 cards (in order) in the end of the bunch, you must take a card. 1 card at the end, 1 taked. 2 at the end, 1 taked. The order must are 1-2-3-4-5-6-7-8-9-10.

I think : means divide?
10 x 10 + 10 - 10 + 10 : 10 - 10 : 10 + 10 - 10 = 100

hmm...are you sure?
10x10=100
100+10=110
110-10=100
100+10=110
110:10=11
11-10=1
1:10=? (Numbers can't go before 0)

According to the mathematical rules, Stigant's solution is perfectly correct

10x10=100
10:10=1
-10:10=1

So

10x10+10-10+10:10-10:10+10-10
=100+10-10+1-1+10-10
=100

oh, besides, 1:10=0.1

Task 5 reminds me of the 24-game, where you must create 24 with 4 given numbers (from 19) using only +, , *, / and brackets.
[edit] All 4 numbers must be used exactly once. Their order may be changed.
Usually these puzzles aren't too difficult, but there are some tricky ones. Some of those are:
1,5,5,5
1,4,5,6
1,3,4,6
3,3,7,7
4,4,7,7
3,3,8,8

But can somebody explain me the 24 game?
I started all ready but I just need to know if I'm heading the right way.

Thanks

For each group of four numbers you have to find a solution using all four of them. Sorry, forgot to state that clearly.

Also, be warned that these are the hardest pairs possible. Most solutions are unique. If you're really stuck:

I didn't say every combination of four numbers has a solution ;).
There are several combinations which cannot be solved following the rules I posted, 1,1,1,1 being one of them.

Well, no it isn't, because you don't use any 2s when writing a square root symbol, like you do with a 3.

there are a lot of things in math, that are there, but not written.

4x+3x+2 means 4.x + 3.x + 2 (multiplication sign)
log 100 = 10 (base of log is 10)
square root (base is 2)
