It is important to remember when you write any formula in Excel having different mathematical operators like +/ -/ ^/  etc, it follows a specific order and performs calculations in specific order which is termed as order of operator precedence. Each of mathematical operator has its precedence and executes in a special order set by Excel.

Explanation:

  • As we already know order of precedence of each mathematical operator is different in Excel. The order of operations for Excel is as follows:

  • Evaluate elements in parentheses.
  • Evaluate 'ranges' ().  
  • Evaluate 'intersections' (empty spaces).  
  • Evaluate 'unions' (,).
  • Perform negation (-).  
  • determine percentages (%).  
  • Perform exponentiation (^).  
  • Perform multiplication (*) and division (/), both are of equal precedence.  
  • Perform addition (+) and subtraction (-), both are of equal precedence.  
  • Evaluate text operators like (&).  
  • Perform comparisons like (=, <>, <=, >=).
