Operator precedence and evaluation ordering

The order of precedence controls the order in which operators in an expression are evaluated. The order of precedence is as follows:

Unary +, Unary -
^
*, /
\
MOD
+, -
&
EQ, NEQ, LT, LTE, GT, GTE, CONTAINS, DOES NOT CONTAIN
NOT
AND
OR
XOR
EQV
IMP

To enforce a non-standard order of evaluation, you must parenthesize expressions. For example:

6 - 3 * 2 is equal to 0
(6 - 3) * 2 is equal to 6

You can nest parenthesized expressions. When in doubt about the order in which operators in an expression will be evaluated, use parentheses to force the order of evaluation.
