1. We are given the equation $? + 16 \times 18 = 247$ and need to find the value of $?$. 2. First, calculate the product $16 \times 18$. 3. Multiply: $16 \times 18 = 288$. 4. Substitute back into the equation: $? + 288 = 247$. 5. To isolate $?$ subtract 288 from both sides: $? = 247 - 288$. 6. Calculate the subtraction: $? = -41$. 7. Therefore, the value of $?$ is $-41$. Final answer: $-41$
