It is\n\n   888\n  +088\n  +008\n  +008\n  +008\n --------\n  = 1000\n --------

81/8 is 10 1/8 don't understand any of the other notations you came up with\n\n1/300 can't be mixed\n\nneither can 1/2

The first three digits are actually multiplied by (80 x 250) = 20000. And you are adding 250 which you have subtracted latter.\n\nIn effect two times the first three digits followed by four zeros. You are adding two times the four digits so you get two times the original number. Dividing it by 2 u get the original value.\n\nYou can do this with 40 and 500, 20 and 1000, 10 and 2000 etc.

You always do what is in the "()" first....\n\n(10x12)+8\n(10x12=120)+8\n120+8\n120+8=128\n128 \n\nGod I used to hate math, now I use it all the time in my job... (Jr. Mechanical Engineer)

186,000  ~~~~~100\n---------- x        ------------   =   ----------/12 = your answer\n  100     ~~~~~~.15\n\nIn other words, multiply 186,000 by .15, and divide your answer by 12.\n\n(the format won't allow me to type the formula as it should be.  Please disregard the "~~~~~~~"

yes multiply and divide by (9+√3)\n√2*(9+√3)/[9^2-(√3)^2]\n√2*(9+√3)/[81-3]\n√2*(9+√3)/78\nis the answer

88 x 132 = (87+1)x132=87x132 + 1 x132=N +132\n87 x 132= N-0

simple!\n(8888-888)/8 = 1000\n\ncertainly I didn't copied rt11guru's answer.\nhere is another one\n\n888 + (8+8)*8 - 8 - 8 = 1000

0000, 0001, 0002, 0003, 0004, 0005, 0006, 0007, 0008, 0009, 0010, 0011... etc, etc  untill u get to 9998, 9999\n\ntry it out, might take a long time but one combination will work :))

the answer would be 62.12\n\n80+50+40+79+61.6=\n\n310.6( numbers added together)/ 5( how many numbers you are adding)\n\n= 62.12

I'd set it up like this...\n36      80\n--   =  --\n n      100\n\ncross multiply and solve for n

Are you able to use any other numbers and operators?  If so this would be fairly easy.  Using only Three 8's and a subtraction symbol it is not possibe\n\nClosest example (8+8)/8-1=1

I think of a number,\n\nX\n\nI multiply the number by 5 and minus 60,\n\n5X - 60\n\nI end up with the number I started with,\n\n5X - 60 = X\n\nSimplify,\n\n4X = 60\n\nX = 15\n\nThe number is 15. (QED)

13212211\n\nJust counting numers in the previous number.\n\n'm i right??

Just add them up using the calculator:\n1000 + 5999 + 9888 = 16887\n\nOr if you don't have a calculator:\n*111\n---------\n**1000\n+5999\n+9888\n=====\n16887\n=====
