Wolfram Alpha gives two different answers for a/ab and 2/2b.

a/ab gives you 1/b.

2/2b gives you b.

Seems like it's an order of operations thing, where the algorith treats ab as a term under the division, but 2b a separate terms, with 2 being under the division and b is separate.

To me:

a
ab

is different than
a/ab

The first it is evident that ab is under the division. In the second, is it:

a divided by ab? or a divided by a times b.

If the former, then it should be written as a/(ab)

Wonder what a/2a would give.

I can see literals being implicitly grouped in Wolfram logic

Essentially this - the formulas are badly constructed mathematical sentences. We don't quibble about the "meaning" behind badly formed sentences...

It restates the input in the first section so you can see what it starts with based on what you typed. Not like it is magic.
