i = 4 ^ 2 * 3 ^ 3 is the same as (4 ^ 2) * ( 3 ^ 3 )

* / \ DIV %

6

i = 4 * 2 + 3 * 3 is the same as (4 * 2) + ( 3 * 3 )

+ 

5


= <> >= <= > < LIKE BEGINS

4

i = 4 + 2 = 5 + 1 is the same as ( 4 + 2 ) = ( 5 + 1 )

OR XOR

2

i = a > 10 AND a < 20 is the same as ( a > 10 ) AND ( a < 20 )

The stronger the operator, the earlier it is evaluated.
If in doubt, rather use brackets to group subexpressions.
