bOperation with lower precedence are evaluate before those with higher. Example: 3 * (4 +5) calculates first the bracket (precedence 1) before multiplying the result with 3 (precedence 3). Without the brackets the multiuplication comes before the addition (precedence 4).
cOperational assignment a (operator)=b is identical to a=a (operator) b. The allowed operational assignment are: +=, -=, *=, /=, %=, >>=, <<=, &=, ^=, |=.
