Hi, You can use SCSubtEqs in the SymbolicComputing package (http://symbcomp.gist.ac.kr, WTC 2011). It is still a beta version, but it might help. <<SymbolicComputing` In[199]:= SCSubtEqs[{a == r, b == s}] Out[199]= a - b == r - s You can use other functions like SCAddEqs, SCMultEqs, SCDivEqs for similar operations. The package was designed to handle primarily manipulation of mathematical expressions rather than evaluation of them. This required some changes, though, like deferred on-demand evaluation of 2-D forms of integrals, products, sums, etc., which are normally evaluated immediately in Mathematica. Please refer to the homepage for further details. Sincerely, Youngjoo Chung
