8.1.5.2 Order of Precedence
When processing mathematical expressions, the order of precedence is:
• Anything inside parentheses ( )
• Exponentiation ^
• Negation (unary) -
• Multiplication *, division /
• Modulo (remainder) MOD
• Addition +, subtraction -
When consecutive operators have the same priority, the expression evaluates
from left to right. This means that an expression such as a-b-c is evaluated as
(a-b)-c.
