order of operations is important but it's impossible to know what exactly do you mean when you write words instead of math symbols, so I would guess that you mean this\n1+1/1-1*1/1=\n\n1+1-1=\n\n1+0=\n\n1

((1/x) + (1/y)) / ((1/x) - (1/y))\n\n((y + x)/xy) / ((y - x)/xy)\n\n((y + x)/xy) * ((xy)/(y - x))\n\n(xy(y + x))/(xy(y - x))\n\n(y + x)/(y - x) = (x + y)/(-x + y) = (x + y)/(-(x - y)) = -(x + y)/(x - y)

The you work it out thus:\n\n0.1 = 10 minus 1\n0.01 = 10 minus 2\n0.001 = 10 minus 3\n1=\n10 = 10 plus 1\n100 = 10 plus 2\n1000 =10 plus 3

1/9(x-1)^9 evaluated from 0 to 2.\n\n1/9(1)^9 - 1/9(-1)^9 = 1/9 + 1/9 = 2/9\n\nIf I didn't screw up.

1/x + y\n______\nx + y\n\nMultiply the top and bottom by x\n= \n1 + xy\n______\nx^2 + xy\n\n\n(x-1)/x divided by ((x^2 -1)/(x+4)\n= (x-1)/x times (x+4)/(x^2 -1)\nFactor x^2 -1 = (x-1)(x+1)\nYou can cancel the (x-1)'s leaving you with\n(x+4)/[x(x+1)]\n\nNote:  For the first problem, if you meant\n1/(x+y)\n______\nx + y\nthen the answer is 1/(x+y)^2

You divide by 0 when you divide by a-b

+/- 1\n\nThe answer is not 1, because -1 * -1 = 1 also.

Well some people say 1+1 is actually 1.99999 because think about it, 1/3 is 0.33333 2/3 is 0.666666 and 3/3 is 0.99999 so 1 is not 1, 1 is actually 0.9999.

If you mean dividing one fraction by another:\n\n(N1/D1) / (N2/D2)\n\nThe answer is:\n\n(N1 x D2) / (N2 x D1)\n\ni.e. (the first numerator times the second denominator) divided by (the second numerator times the first denominator)\n\nThe reason is that dividing by a fraction (F) is equivalent to multiplying by (1/F). So another way of thinking of the problem is:\n\nTurn the second fraction upside down\n\nThen MULTIPLY these fractions, numerator by numerator, denominator by denominator

the right answer is 3 because the order of operations is this: first u divide 2 by 2, and that get's 1; after that, add 1 at 2 and u get 3.\n\nAlways the division or * is the first operation u make. After that u make the + or -.

1...anything multiplied by 1 is itself...so in division anything divided by itself is 1
