It is the same use of "for" as in the sentence "there are chairs for all the visitors".  This would also mean "there is a chair for each visitor", and the sentence you are quoting would have been better if it had said "there is a combined operator for each binary operator".\n\nAn example from C is "a = a + b".  The 'plus' is a binary operator, using the value of 'a' in the expression a+b and setting 'a' to the result of the expression..  The combined operator for it is the character pair '+=' seen in "a += b".

lol okay I'll try to explain first of all its [()] only when nessary which is rare.\nNow it gets kind a weird but () can be used both in the middle and at the end of a sentance (with the period like this). But only if its short. (I know its weird but if whats inside is a complete idea and not a momantary pause with short bit of info it can actually go like this.) Hope this helps.

Half of "one and a half" is three-quarters.  Twice "three-quarters" is "one and a half."\n\n... seems to me.

(the half of 2) plus 2\nor\nthe half of (2 plus 2)?

It is reflexive because\naRa\n|a-a|<=2\n|0|<=2\n0<=2 is true\n\nIt is symmetric.  If aRb, then bRa\n|b-a|<=2\nFor absolute value |b-a|=|a-b|; therefore,\n|b-a| = |a-b|<=2 is true.\n\nIt is not transitive.\nIf aRb and bRc, then aRc. This is not necessarily true.\nAssume |a-b|<=2 and |b-c|<=2 are true.  Does it follow that |a-c|<=2?\nJust give one example of why this is false.\nLet a = 2, b = 0, and c = -1, then\n|a-b|<=2 becomes |2-0| = 2 <= 2, which is true.\n|b-c|<=2 becomes |0-(-1)| = 1 <= 2, which is true.\n|a-c|<=2 becomes |2-(-1)| = 3 <= 2, which is false.\nHence, it is not transitive.

Duh! All keyboards have the 2 and @ on the same key, same with ' and "! It's suposed to be like that!

T1=m1*a, no matter are there m2 & m3 or not.\nT2=(m1+m2)*a, no matter whether m1 & m2 are connected with a string or are in one lump, the presence of m3 being unimportant too.

A is the answer.  The other answers doesn't make sense at all.\nI just learned this stuff 3 years ago!

First answerer correct.  \n\nBut the second set is a function, because there are no repeated x values.  If you have a component of the first set corresponding to two different components of the second, then it isn't a function, e.g. in the second set, if the next pair were (15, 5) then it wouldn't be a function because of the double result for 15.  In the first set, if your misprinted pair were (1,2) then it wouldn't be a function, same reason.

R, S and T as consecutive letters are used to name the 3 different phases. I am not sure why they those 3 have been chosen.

Its the same with two, too and to.  Drives me insane.  I cant believe people still get this wrong.

in decimal its 2\nin binary its  0\nin other like octal hexa etc its 2\nin logical or its 1\nnow wat do u want????

I can work the 'dr' bit out but I'm lost on the 'b/c' bit? \nPlease elaborate I'm puzzled!

In boolean logic, a rule says: A + A = A (see: http://en.wikipedia.org/wiki/Boolean_algebra if you don't believe)\n\nThus if A equals to 1:\n1 + 1 = 1\n2 = 1\n\nNOTE: Wikipedians uses v and inverted v to represents the use of AND and OR logic, I am used to use + and . (multiplication dots), and I think this is the more correct one than wikipedians, since the equation being done here is more in boolean algebra and not only boolean logic

everything that interprets 1s and 0s into something you can use is an operating system, the difference is the architechture, ex:windows is x86

0.1(6) ---> point one six - the six repeating\n\n0.(16) ---> point one six - one and six repeating\n\nNotice:\n1) the parenthesys notation is a standard, and it works well even when you don't have special characters, as on Y!Answers...\n2) when things get ambiguous, like in this case, it is a duty to spend a little more words to make things comprehensible; so you could well say "one point six repeating" for the two, as you noticed: it's not wrong for any of the two, but you yourself felt the need to specify better, so you can spend words and specify what you exactly mean. Otherwise, use standard notation
