Precedence of Operators

The precedence of operators is:

Precedence	Operators
1	parentheses (inner to outer)
2	multiplication, division, negation
3	addition, subtraction
4	comparison (relational operators)
5	AND, OR, NOT (logical operators)

Operators with the same precedence are evaluated left to right.

1 + 2 * 3 // equals 7, not 9
