these people dont know without seeing your page. it depends on many things, like if you used a editor or not. the best way would be to ask the people that made the puzzle.

There are an infinite number of ordered pairs that would satisfy this equation. If you want to find a few of them, assign a value to x and then solve for y.

I don't think you have stated the puzzle correctly.\n\nIf each letter is supposed to represent a single digit, (which is the usual way these kinds of problems are stated) and the correct statement of the arithmetic is\n XYZXYZ+ABCD-ABC=EFGHA\nthen there is no solution.\n\nXYZXYZ is a 6 digit number, since ABCD has to be larger than ABC, ABCD-ABC is a positive number.\nWhen you add that to XYZXYZ, the result will have at least 6 digits, but EFGHA only has 5 so the problem is inconsistant.\n\nThere is another problem: The puzzle as you have stated it, uses 11 symbols to represent the 10 digits. If you allow more than one letter to represent a single digit then you can say let all the letter represetn the same value. Then you can get: A=B=C=D=E=F=G=Z=Y=Z=0 and the problem is trivial.

The puzzle is looking for a word for worm.  I think it is probably Platyhelminthes.  This is 15 letters, so maybe the puzzle should say 15 instead of 13.  Maybe there is some other type of worm that they are looking for.  Other possibilities include Chaetognatha (12 letters)

Nothing's hidden inside, but it's an ambigram.  Print it out and turn it 90 degrees and see what happens; then 90 more, then 90 more.  You will see something cool.

NO\nthats the answer..... it doesn't say "What am I?" it says "Can you guess the riddle?" so the answer is "No"....

Did a teacher tell you this and now you wonder?  Or is this a mathematical riddle?\n\nIf the former, I don't see the inconsistency.  If the latter, I can't wait for the punchline.

OMG a math riddle I cant seem to answer!!!! :-)  Awesome. I cant sleep because now i want to knwo the anwer. And so i continue to try and solve it.\n\nBest i can come up with is 113  or 240 or 50-something..\nAlso maybe another number in the 100-n-teens\n\nI did find a 1-3-4 pattern aasuming the next number in 1-3-4-1 was a 3 but was unsure of how to continue it. (its1230 in the moring here)\n\nAnd again another possible patter 1-3-4-8 next number would be 16.\n\nI know some may not even know how I came up with these, but I love math and I love a challenge. I have been trying to find any possible correlation in the numbers that I can. \n\nHope someone figures it out. I know I cant wait to see the answer.

The answer to the puzzle is probably "language".  This is from a common chain-letter puzzle, which is phrased as a trick question.\n\nVisit the source link below for more detail.
