• A. 26
• B. 17
• C. 65
• D. 11

Answer 1

Answer:

C. 65

The value of the expression is 65.

1. Substitute the operators according to the given rules:

   • Change + to ×

   • Change ÷ to +

   • Change - to ÷

   • Change × to -

   The expression 9 + 8 ÷ 8 - 4 × 9 becomes:
   $9 \times 8 + 8 \div 4 - 9$

2. Solve using BODMAS / PEMDAS rules (Division, Multiplication, Addition, Subtraction):

   • Division first ($8 \div 4$):
     $9 \times 8 + 2 - 9$

   • Multiplication next ($9 \times 8$):
     $72 + 2 - 9$

   • Addition and Subtraction last ($72 + 2 - 9$):
     $74 - 9 = \mathbf{65}$
