Hi folks, This post is related to a previous series of posts about ReplaceAll in a set of inequalities. I have "reduced" the problem to this unexpected situation: In[1] FullForm[-3<=x<=1] Out[1] LessEqual[-3,x,1] In[2] Reduce[-3<=x<=1] Out[2] -3<=x<=1 In[3] FullForm[%2] Out[3] Inequality[-3, LessEqual, y, LessEqual, 1] In[4] Reduce[ LessEqual[-3,x,1] Out[4] -3 ≤ x ≤ 1 In[5] FullForm[%4] Out[5] Inequality[-3, LessEqual, y, LessEqual, 1] This defies my understanding. What is qoing on with Reduce? Jack
