as a newbie to Mathematica I wonder if someone can help...
I'm generating a puzzle worksheet for some students and wish to add linear rational expressions, three at a time from a pool of six.
I want to be able to swiftly add (a) + (b) + (d) for example, or (b) + (d) + (f)
Can I store the expressions and add them as I have done here. I've not had much success so far. I'd like to have a worksheet which I could tweak expressions a - f without then having to manually copy & paste endlessly into arithmetic expressions.
I'm then combining them with
ExpandNumerator@Together[%] ExpandDenominator[%] // TraditionalForm
And will give the output to the student for Partial Fraction Decomposition.
