For example, in the statement "4 + 28", the 2 will first be multiplied by 8 and then the result will be added to 4. This is because the "*" has a higher precedence than the "+". To avoid ambiguity in reading the program, it is recommended that is statement is written as "4 + (28)"

"4 + 28" and "4 +(28)" should be "4 + 2 * 8" and "4 + (2 * 8)"

It's supposed to be about operator precedence. Placing "( )" would not show how the precedence of "+" and "" works.

They are actually missing in the documentation. My point is: "" operators are missing in the documentation. So the documentation and my suggestion is correct, as far as paranthesis goes but the * operators are missing. Hope that is clearer now.
