I don't understand what is surprising about -5 mod 4 being the same
as -(5 mod 4). After all, you expect -x to be the same as 0-x,
and 0 - 5 mod 4 is
<operand 1> ADD <operand 2> MULTIPLY <operand 3>
which naturally groups as
<operand 1> ADD (<operand 2> MULTIPLY <operand 3>)
The grouping, at least, is identical in Pascal.
