Re: [sage-support] how to get a list of terms of expression such as x+z^2 in gap system

thank you. actually i mean in gap system i solved with poly1 := 0; for j in [1..Length(prepoly1[1])] do zz:=1; for i in SplitString(String(prepoly1[1][j]), + ) do zz:=zz*EvalString(i); od; if zz 1 then poly1 := poly1 + zz; fi; od; vdelecroix於 2014年9月28日星期日UTC+8下午5時24分34秒寫道：
