Can someone offer an explanation for the following output?---I'm trying to understand why it makes sense for Mathematica to be set up to respond like this. (Of course, feel free to point out any glaringly obvious math examples.) In[1]:= {a == a, a <= a, a >= a, a < a, a > a} Out[1]= {True, a <= a, a >= a, a < a, a > a} I would have thought that a <= a and a >= a would both evaluate to True, given that a == a does. Also, can something really be greater than itself? Hmmm... maybe there's hope for me after all. :) -RG
