 ## Operator precedence
 
-If an expression has more than one operator, the execution order is defined by their *precedence*, or, in other words, the implicit priority order of operators.
+If an expression has more than one operator, the execution order is defined by their *precedence*, or, in other words, the default priority order of operators.
 
 From school, we all know that the multiplication in the expression `1 + 2 * 2` should be calculated before the addition. That's exactly the precedence thing. The multiplication is said to have *a higher precedence* than the addition.
 
-Parentheses override any precedence, so if we're not satisfied with the implicit order, we can use them to change it. For example: `(1 + 2) * 2`.
+Parentheses override any precedence, so if we're not satisfied with the default order, we can use them to change it. For example, write `(1 + 2) * 2`.
 
 There are many operators in JavaScript. Every operator has a corresponding precedence number. The one with the larger number executes first. If the precedence is the same, the execution order is from left to right.

-Funny code, isn't it? We should understand how it works, because sometimes we see it in 3rd-party libraries, but shouldn't write anything like that ourselves. Such tricks definitely don't make code clearer or readable.

 Please note that the comma operator has very low precedence, lower than `=`, so parentheses are important in the example above.
