268=(6-(6+6)/6)*(66+6/6). Can you make it with seven sixes or less?

You just have to list all the possible answers until you get 6 (your lowest number) in a row without skipping one.  After that you could get the next six by adding the 6 to those six.\n\nYou can get:  6, 11, 17, 18, 22, 23, 24, 28, 29, 30, 32, 33, 34, 35, 36, 38, 39, 40, 41, 42, 44, 45, 46, 47, 48, 50, 51, 52, 53, 54, 55.  There are 6 in a row.  So the highest you CAN'T get was 49.\n\nIt only works if the two numbers are relatively prime (they have no common factors besides 1).  The formula for finding the number is:\n\n(higher number) times (lower number minus 1) minus lower number\n\nHere that is 11(6-1) - 6 = 11(5) - 6 = 55-6 = 49

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

First you need to do 9 + 6 which equals 15 then multiply that by 4 and you would get 60. The second way that you would solve that is by distrubuting that means you multiply 4 x 9 which equals 36 then 4 x 6 which equals 24 and add them together 36 + 24 equals 60.

a) -6(a+5b)-3(-7b-a)\n=-6a-30b+21b+3a\n=-3b-9a\n\nb)6(a+2b)+8a-16b\n=6a+12b+8a-16b\n=14a-4b

7\nbecause\n6m+5=47\n.....-5 -5\n   6m=42 (divide each side by 6 and u get 7 {42/6 =7)

its impossible because there needs to be either one less sign or one more number look:\n\nin a the order:\n2 * 4 - 6 + 8 /\n              ^there is an extra sign!!

First one: Factors to (6a+7)(6a-7)\nSet one equal to 0...6a-7=0\n6a=7\na=7/6 ...or 1 and 1/6\n\nSecond one equals x-8 over x-3 times 3-x over x-3\nThen you can multiply and simplify\n(x-8)(3-x) / (x-3)(x-3)

That's an extremely good question. \n\nThe answer is simple. Before that, i will explain what your question means to those who don't get. Well, it means that we must get 24 using 1,3,4 and 6 any number of times however involving operations +,-,* and / only once. \n\n  Then, the answer is very simple :\n\n  {[(6*6)/(3-1)]+[6]}  =  24\n\n---------------------------------------------------------\nWOKRING :\n\n {[(6*6)/(3-1)]+[6]}   =  {[(36)/(2)]+[6]}\n                       =  18 + 6\n                       =  24\n\n----------------------------------------------------------\n\nI hope you post more questions like these. They evoke a lot of thought. I hope the solution serves th purpose.

Don't be scared by all the words.  You just have to remove brackets and parentheses from\n2[x+(x+10)+(x+2(10))] \n\nand then collect the terms -- you should get 6x+60.\n\nThe last part just means do it again with 15 replacing 10.

Simply multiply\n9 * 8 * 7 * 6\nBecause the first number can be 1-9 but not zero and the second number can be 1-9 but one number has already been used and so on and so forth.\nHope it helps.
