24. Order of Precedence

• Operators can have

  • the same precedence

  • higher precedence

  • lower precedence

  when used in combination. For example, an expression

  
      2 + 3 * 4 // yields the value of 14
  
  

• This is because multiplication operator has higher precedence than addition.

• A programmer can override the built-in order of precedence by grouping subexpression with parenthesis:

  
      ( 2 + 3 ) * 4 // yields 20.
  
  

• When operators have the same level of precedence, operations are performed from left to right
