💡 Analysis & Explanation
BODMAS Rule Application
To systematically evaluate the given arithmetic expression without errors, the strict hierarchy of operations (Bracket, Order, Division, Multiplication, Addition, Subtraction) must be adhered to.
Division Execution
According to the hierarchy, we first isolate and execute the division operation present in the string: 76 / 2 = 38.
Sequential Addition and Subtraction
The expression now simplifies to 81 + 38 + 42 - 86. Executing the additions linearly from left to right gives: 119 + 42 - 86 = 161 - 86. Finally, subtracting the terminal value yields 75.
Conclusion
The completely simplified numerical value is 75.
