The explanation I see is that on answers 1,3,4,5,6 implicit data types conversion happens because of mixing INT and CHAR types.

On the answer 2, we just try to multiply 2 CHAR, therefore an error is raised up.

Good question!

Yeah, I have to agree, multiplying strings is the cause. It errors before it even tries to implicitly cast the answer to an int.

I particularly like the fact that a QOTD was verified by several people before publication.

It gives me this error on the 2nd block

Msg 8117, Level 16, State 1, Line 3
Operand data type char is invalid for multiply operator.

I guess E stands for ERROR?

This kind of error also is independent from version of sqlserver.
You can not use - * / operators with chars

Yet another question that tells us not to rely on implicit conversion...
