Hi,
I am new to Mathematica and sorry if this is too simple.
Out56 seems to say that we can add {1} to 1, so we have {2}.
Out57 says we can not compare {1} to 1.
I 'd like to know, elements in Out55, are they sets/list or numbers?
Is there a simple way to check the types of the outputs? (tells me whether they are Tables, Array, Functions, Procedures, Numbers)
Thanks!
