💡 Analysis & Explanation

Symbol Translation ▼

Mathematical puzzles of this type require replacing the printed symbols with their newly assigned operative values before attempting any arithmetic.

Execution Strategy ▼

By carefully substituting the newly defined division, multiplication, addition, and subtraction signs into the equation string, we formulate a fresh, executable arithmetic expression.

Applying BODMAS ▼

Following the strict universal hierarchy of mathematical operations—handling all division first, then moving to multiplication, addition, and finally subtraction—the numbers collapse downward systematically.

Target Evaluation ▼

Processing the corrected logical string perfectly resolves to the officially credited target number.

Conclusion ▼

The resultant mathematical value evaluated is exactly 492.
