Precedence table

index
ADVANCED

Precedence rules tell in what order operations are done. For example, the rules tell you that 2+3*4 is 14, not 20.

Every programmer should know the basic rules of precedence. For operators not covered by the basic rules, it is considered good style to use parentheses to indicate the order of operations, even when those parentheses are not necessary; this makes your code more readable by programmers who do not have the following table memorized.

Entries nearer the top of the table have higher precedence (are done first); entries on the same line of the table have equal precedences.
