A. 72
B. 71
C, 74
D. 75

Options

A. C
B. A
C. D
D. B

Answer

To solve the expression `36 - 4 + 7 x 8` with the given meanings of the operators, we will follow these steps:

### Step 1: Replace the operators with their meanings
- The operator `-` means `div` (division).
- The operator `+` means `X` (multiplication).
- The operator `x` means `+` (addition).

So, we can rewrite the expression as:
\[ 36 \div 4 \times 7 + 8 \]

### Step 2: Perform the division first
According to the order of operations (BODMAS/BIDMAS), we first perform division:
\[ 36 \div 4 = 9 \]

### Step 3: Rewrite the expression
Now, substitute the result back into the expression:
\[ 9 \times 7 + 8 \]

### Step 4: Perform the multiplication next
Now, we perform the multiplication:
\[ 9 \times 7 = 63 \]

### Step 5: Rewrite the expression again
Now, substitute the result back into the expression:
\[ 63 + 8 \]

### Step 6: Perform the addition
Finally, we perform the addition:
\[ 63 + 8 = 71 \]

### Conclusion
The value of the expression `36 - 4 + 7 x 8` is **71**.
