What is the solution to this equation involving cats, dogs, and lambs?

[Bad_Boy_Blue]

If cats + dogs = lamb, what does dogs equal?

Please simplify your answers as I'm finding this concept rather difficult to get my head around.

Surely you just move the cats to the other side of the equals sign. Right?

Is this a problem where every letter is assigned a digit? And thus this problem is the sum of two four digit numbers? Or is it something else entirely?

If it is what chroot is suggesting it is, it looks hard to figure without using a computer. Making a few simple eliminations (O=0 or 9), reduces the number of possibilities to about 10^5 - notice that there are 10 different letters, so all the digits must be used. Hmmm...looks like a toughie.

Are you just making up a generic example off the top of your head, or is this the exact question from a book or homework ? If the former, there may be no solution at all, and even if there are solutions, they may not be paper-and-pencil-able.

Are you allowed to write a program ?
