It's for expressions that the parentheses are not required.
The operand of the sizeof operator is either a unary-expression
or a parenthesized type name.  (You can use parentheses with the
expression, but then they're part of the operand, not part of the
syntax of sizeof.)

You appear to have tremendous difficulty learning things like this,
even after they're explained multiple times.  I don't believe you
really have such difficulty.  I think you're just pretending for
the sake of making a strawman argument.  It's getting old.
