Expressions can be combined using operators. Each operator as a precedence priority. Here is the list of those expression’s priority.
These operators can do some logical comparison between other expressions:
or, || and, && true or false and true
The and operator has more prioroty than the or, thus in the example above, false and true is evaluated first.
=, ==, !=, <> <, <=, >, >= [Total] < 2000
+, - [Total] + [Tax] > 3000
*, /, % [Price] * [Quantity] == [Total]
& (bitwise and), | (bitwise or), ^(bitwise xor), << (left shift), >>(right shift) [Field1] >> [Field2] > 5
!, not, -, ~ (bitwise not) not true
(, ) 2 * ( [Field1] + [Field2] )
