Choose the most appropriate option for the blank. \((-9) [55 \div \{6 - (- 5)\}] = \_\_\_\_\)
-45
-45 is correct.
Expressions with mixed brackets are evaluated by resolving the innermost bracket first and then working outward, following the BODMAS order of operations.
Here the innermost bracket is \(6 - (-5) = 6 + 5 = 11\). The next bracket then becomes \(55 \div 11 = 5\). Finally, multiplying by the outer factor gives \((-9) \times 5 = -45\). Hence, the value of the expression is -45.
