Evaluate Equal Precedence from Left to Right

When there are two (or more) operators of equal precedence, the expression is evaluated from left to right. Examples: 


2 * 7 * 3 
-----
  14  * 3
  -------
     42


4 - 2 + 5
-----
  2   + 5
  -------
      7

Usually it doesn't matter if evaluation is done left to right or in any other order. In algebra it makes no difference; But with floating point math it sometimes makes an important difference.

QUESTION 24:

What is the value of the following expression?
