Hi, I have an expression that is a sum of terms, like a+b+c and I want to convert it to a list, with as many elements as the number of terms in the sum of terms, and with each element being each of the terms, like {a,b,c} Also, the same to go from a product of terms like a*b*c to a list like {a,b,c} Is there any way, in Mathematica, to do this? I've been looking for an answer in the Help, and in the web, with no help. I ask this because "a*b+c+e*f*g" needs to be evaluated by an external (.NET) program, which is not able to parse expressions. I have to "break" everything inside Mathematica, before sending information to that external program, which will evaluate that expression many times, for different values of {a,b,c,d,e,f,g}. Thank you.
