Solution

Break Down the Problem

  1. Identify the components of the expression:
    • Variables: result, total, count, max, offset
    • Operations: Division, multiplication, and subtraction.

Relevant Concepts

  1. Understand operator precedence in programming:
    • Parentheses () have the highest precedence, followed by multiplication * and division / which have the same precedence (evaluated from left to right).

Analysis and Detail

  1. Analyze the expression step by step:
    • The operation inside the parentheses (max - offset) will be executed first because it is given the highest precedence.
    • Next, total / count is evaluated since both division and multiplication have the same precedence — they are executed from left to right.
    • Finally, the multiplication of the result from total / count with the result from (max - offset) will be calculated.

Verify and Summarize

  1. Verify the order of operations:
    • First: (maxoffset) (max - offset)
    • Second: (total/count) (total / count)
    • Third: result=(total/count)(maxoffset) result = (total / count) * (max - offset)

Final Answer

The operation executed first in the expression result = total / count * (max - offset); is the subtraction inside the parentheses: (maxoffset) (max - offset) .
