Operator precedence includes unary, increment, basic arithmetic, logical and assignment operators  roughly in that order.
The precedence can be remembered by BEUDMASLAS.
 brackets
 exponent
 unary & prefixed increment / decrement
 division
 multiplication
 addition
 subtraction
 logical
 assignment
 suffixed increment / decrement
Not quite exciting as BODMAS or PEDMAS (math, anyone?) and as it turns out  you would not even have to remember it :).
An outline with examples is below.
Type  Operator  Description  Example 

Brackets  ( ) 
Two brackets to rule them all  10 / (2+3) 
Exponential  ** 
2 ** 2 

Unary & friends  +  ++  
Unary operators, pre increment/decrement  ++i , j 
Arithmetic  % * 
Binary arithmetic operations  i / j 
Arithmetic  +  
Needs no explanation  i + j 
Logical  ! &&  
Logical operators in order of precedence  i && !j 
Assignment  += = *= /= 
i += 1 

Assignment  = 
Let there be assignment (at the end)  
Post incr./decr.  ++  
Changed value available to next operation  i++ 
Golden rule: put brackets whenever in doubt.
Priceless rule: Use prettier (and you should). It will automatically put brackets to clarify precedence and make the expression readable.
Let us look at some examples
