💡 Analysis & Explanation
Applying Core BODMAS Principles ▼
The inviolable rules of basic arithmetic sequence dictate that operations enclosed within parentheses must be aggressively resolved before any external calculations. Therefore, we first calculate the inner sum: (17 + 6) = 23.
Execution of Multiplication Phase ▼
Substituting this newly found integer back into the main equation generates the updated string: 127 - 7 × 23 + 93. According to the hierarchy, we execute the multiplication next: 7 × 23 = 161.
Final Addition and Subtraction ▼
The expression is now heavily simplified to 127 - 161 + 93. Reordering the terms for maximum computational ease, we group and sum the positive integers first: 127 + 93 = 220.
Conclusion ▼
Finally, we subtract the remaining negative value from this sum: 220 - 161, which provides the mathematically correct and verifiable answer of 59.
