The '+' operator is special in the sense that
it converts its right
operand to the type of the left operand and the result also has the type
of the left operand. The other operators force conversion
and always have a fixed return type (e..g '*' converts both of its
operands to int and always returns int).
More examples:
"1" + 2 = "12"
1 + "2" => error
"1" + "2" = "12"
"1" * 2 => error
1 * "2" => error
"1" * "2" => error
Why are these errors? You said "The other operators force conversion"

(int)"1" * 2 = 2
