Operator precedence

Expressions are evaluated according to the hierarchy of operators.

The table below displays the hierarchy of operators with the highest precedence operator shown first.

Expressions inside parentheses are evaluated first; nested parentheses are evaluated from the innermost parentheses to the outer.

Operators in the same row in the chart have equal precedence.
Operators	Type	Order of Evaluation
( )	Parentheses	left to right
- +	Unary minus and plus	right to left
* / %	Multiplicative	left to right
+ -	Additive	left to right
&	Concatenation	left to right
< > <= >=	Relational	left to right
= <> <=>	Equality	left to right
