67*18/6+17-18=200 is correct mathematically and it follows the order of precedence.\n\nOrder of Precedence can be easily remembered by the expression "Please Excuse My Dear Aunt Sally".  You follow (P)arenthesis, (E)xponents, (M)ultiplication, (D)ivision, (A)ddition, then (S)ubtraction.\n\nThere is no parenthesis or exponents in this problem.\n\n67*18/6+17-18=200\nMultiplication first: 1206/6+17-18\nDivision next: 201+17-18\nThen addition: 218-18\nSubtraction lastly: 200\n\nProblem solved!

99.\n\n2-55 can be thought of a 2 and then a matching tens and ones place 3 digits higher.\n\n6-xx then, can be thought of as the x being 3 tens and 3 ones higher than 6, ant that' 6-99, making 99 the answer.

18 / x = 24 / 100\n18 / x = .24\n18 = .24x\n18/.24 = x\n75 = x

Just subtract 27624824 from both sides, leaving the answer as 7497211600

Only a few answers are possible. One of those is 18, which is used in the example.  All of the possible answers have the same symbol as 18.\n\nSorry, I don't know how to prove this, but try a few examples, always comparing the symbol representing your result to the symbol representing 18.\n\nOkay, I figured it out. \n\nState the puzzle another way:\n\nChoose two one-digit numbers, x and y.\n\nCalculate 10x + y - x - y = 9x\n\nThe result of every calculation is merely 9x.\n\nIn the chart, every multiple of 9 is represented by the same symbol, so no matter what numbers you choose, you get the same symbol.  \n\nWhen you click on the "Click here to try again" link, it merely redraws the table with a different symbol representing the multiples of 9.

In Custom format you can specify format as required by you.\nIt has three parts seperated by ;\n1st is for positive\n2nd is for negetive\n3rd is for Zero\nso you can specify as  follows to get the + sign displyed\n\n+#;-#;"Zero"

What's with the ... ? Is that a space for a number, are you supposed to guess whether to use the + or the x ? I don't get it, I think I'm gonna cry :~(
