AP Computer Science A Standards: Expressions evaluate according to operator precedence (e.g., multiplication, division, and modulus take precedence over addition and subtraction) and associativity (left-to-right for most arithmetic operators, right-to-left for assignments). The sequence of prefix and postfix operators dictates exactly when a variable's value is updated in relation to the larger expression. Casting applies based on its proximity unless overridden by parentheses.
