Math puzzle. Use any mathematical sign between the numbers to get "6" as an answer.?

Do you require mathematical signs, or are standard operations OK (like square root)?\n\n1: (1 + 1 + 1)!\n2: 2 + 2 + 2\n3: 3 * 3 - 3\n4: sqrt(4) + sqrt(4) + sqrt(4)\n5: 5 + 5/5\n6: 6 + 6 - 6\n7: 7 - 7/7\n8: 8 - sqrt(sqrt(8 + 8))\n9: 9/sqrt(9) + sqrt(9)\n\nAnd for a bonus: (0! + 0! + 0!)! = 6

well we know the 3 space must be even, in order to avoid the last space resulting in another 5\n\nhmmm... i'l work on it, provided you're working as well!\n\n..and #3 mustn't be 0, to avoid another 0\n..lol i'd have had it if i had been home...i made a program to do it, and then left before i finished/ran it lol\n\nbut that, is of course, the correct asnwer, 396*45=17820\n\nhaha thanx for the challenge!

6 because 6*7=42 and 6*9=54

first you figure out the number of possible outcomes you can have. which would be 6x6 = 36. \nThen you figure out how many combinations you can make to make it greater than 7:\n5 and 3\n5 and 4\n5 and 5\n4 and 4\n4 and 5\n3 and 5\nwhich is 6.\n6 over 36 is one sixth. therefore your answer is 1/6.

Alright, I've got two answers using the four basic operations:\n\n(14 - 6) * 3\n\nand\n\n(6/(1-(3/4)))\n\nIf you allow other operations, there are a few more answers (! is the factorial symbol : 4! = 4*3*2*1, 3! = 3*2*1, etc)\n\n4*1*sqrt(36)\n(3*6-14)!\n16*3-4!

Write down the symbols of several of the other numbers-symbol combinations first then click the silver ball. You will see that the symbols changed. Next on the new page do the math that you were told to do on the first page for several different 2 digit Numbers. You will see that on the page of symbols it is impossible to do the math that they ask you to do without coming up with the same symbol as the symbol that will later be in the Chrystal ball. The math leads to, as the above answerers have said, a multiple of 9. \n\nIt is just that the human mind doesn't really remember what all of the symbols were, so it doesn't recognize that every time you reset the page it has been restacked to give a different symbol, thus giving the illusion of always being right. Also, people seldom will try doing the same number twice, but if they did they would quickly see through the trick because if you picked the same number twice in a row you would realize that the same number lead to a different symbol.\n\nBy the way good job to those above answerers for the math involved I prefered to just explain the trickery.

Ok, I got it.  I recommend writing the numbers 1-12 and crossing them out as you use them.\n\nYou've got your 5,6,1,and 8 on the inside.  So on the upper row of four, 5+6=11, so you need 15 more to make 26.  The only numbers that are left where 2 add up to 15 are 12&3 or 11&4.  I tried 11&4 first and will just tell you it didn't work, so it's 12&3.  Now to decide which goes where.  If you put the 3 on the left, it lines up with the 1 making 4, and there's no other numbers that will add up to the required 22 - so 12 must go on the left and 3 on the right.\n\nNow you can see the line  from the bottom point up to the 3.  8+3=11, so you need 15 again, and the only choices left are the 11&4.  Put the 11 at the bottom point and the 4 between the 8&3.\n\nNow looking at the line that goes from 12 down to the 11 you have 12+1+11=24, so you must use the 2 here.  Now you have 7,9 & 10 left.\n\nLooking at the line with the 5&2, that makes 7, so you need 19.  The only way to get that is with the 10 & 9, but you don't know which goes where.  You DO know, though, that the only other point that is left gets the 7.  That's the bottom right point.\n\nThis made a line with 7,6,4 and the very top point.  7+6+4=17, so you need 9 at the top to make 26, which leaves the space for the 10 at the bottom left.\n\nIn order, from top to bottom/left to right you have\n\n9\n12,5,6,3\n2,4\n10,1,8,7\n11

6, 10, 11, 20, 24, 40, ...\nThe diff between 6 and 10 is 4\n10 & 11 = 1\n11 & 20 = 9\n20 & 24 = 4\nso it's 4, 1, 9, 4\n4 and 9 and 1 are perfect squares, so just follow the pattern!

(n/(n - 3)) + (5/(2n - 6))\n(n/(n - 3)) + (5/(2(n - 3)))\nMultiply everything by 2(n - 3)\n(2n + 5)/(2n - 6)

Adding and subtracting:  You use the sign from the largest number.\n\nIn your example: 8x +6x + 2 + 10\nAll are positive.  You have 14x + 12\n\nLet's say you  have 8x - 6x.  the 8 is bigger and is positive so your answer is positive.  It's 2x.\n\nNow try 6x - 8x.  The 8x is negative and is the larger number.  So it is going to be negative.  The answer is - 2x.  \n\nIf multiplaying or dividing:\n\n+ and + is +\n+ and  - is -\n-  and -  is + \n\nYou must have to memorize those.  Remember, it's always positive unless one sign is positive and one negative.  Then it is negative.\n\nBest Wishes,\nSue

This is more of a word problem or a riddle than a math problem.\n\nThe answer is 7 (SEVEN).  Remove its first letter and it becomes EVEN!

Here's how to work it out:\n\n(Sorry, because I can't use special symbols, I'm using _/ for the square root symbol and <= for the less than or equal to symbol.)\n\n_/3x + 6 + 4 <= 7\n_/3x + 10 <= 7\n3x + 10 <= 7 x 7\n3x + 10 <= 49\n3x + 10 - 10 <= 49 - 10\n3x <= 39\n3x/3 <= 39/3\nx <= 13
