Can someoned please explain this math riddle?

Quoting by Eric V:\n"From Sum's first statement we know that x+y is a sum none of whose possible components are both prime (x+y is not even)"\n\nin fact, from Sum's first statement, the significant deduction is that x+y is not even. And you deduce it just because if it were even, there would be a possibility that the two numbers be both odd, and among this there would be the possibility that x+y were both prime: so if x+y were even, Sum would not be able to be sure that Prod could not know the numbers.\n\nPay attention:\nYou're not saying that x+y even ---> x and y not prime.\nYou're saying that x and y both prime ---> x+y even\n\n(Anyway an additional and not told assumption is that x and y are > 2)

Sounds like a Math/Science type question to me. Why are you posting it here?\n\nBesides, I have the the slightest idea.

1+1=2. That's it. The answer for everything else would be simply 42

To a mathematician 1 + 1=2 right. If I were using that equation in another context it could be interpreted differently. In a nutshell the quote is saying that people sometimes interpet the same one thing differently.

3/x  + 1    the way you put it..

Ok, take it back.\n\nFlip the 6, turn it into a 9.  Move it over to the right hand side, move the 2 to an exponent over the 7.\n\n7^2 = 49.\n\nThat's it.

What does this have to do with math?

This is more of a word problem or a riddle than a math problem.\n\nThe answer is 7 (SEVEN).  Remove its first letter and it becomes EVEN!

I can explain this with simple mathematics..\nLet the number u choose be 'x'.\nNow double the'x' and adding 12 gives us:\n2x + 12.\nDividing this expression by 2 gives us:\nx + 6.\nSubect the no. u thought i.e. 'x' from this and what u get is 6.\nAm I correct Ma'am?

I POSTED THE FIRST CORRECT ANSWER HERE AND WAS WRONGLY DELETED FOR A BOGUS VIOLATION REPORT\n\nI posted last night around 12pm, here was my (correct) answer:\n\nOk so let the tens digit be x, then the ones digit is (12-x). The value of the number is 10*x+(12-x) = 9x+12 which you are told = 11x 9x+12=11x 12=2x x=6 12-x=6 also So the number is 66. (Check x = 6*11 as claimed.)\n\n(There is some severely dishonest point-gaming going on around here)

You may have miss-typed the riddle!\nThe question should be:\n8 _ 4 9 1 _ _ 10 3 2 0\nIf that is the case then the answer is:\n8 5 4 9 1 7 6 10 3 2 0\n\nReason: This list of numbers is in alphabetical order

Pressure!!!!!!!!!! Oh my gosh, I am soooo sick of seeing this riddle! Its been on here about 100 times!

Cool.  Just recall what our place value number system means.\n\n0 is in the 1s col, so it's absent\n3 is in the 10s col, so c = 1\n1 is in 100s, so a =2\n4 is in 1000s, so d =3\n2 is in 10,000s so b=4
