1. **Stating the problem:** We have numbers 624, 1000, and 2 arranged with an arrow pointing down to 248. We want to understand the relationship or operation that leads from these numbers to 248. 2. **Analyzing the numbers:** Given 624 and 2 on the sides and 1000 in the middle, and the result 248 below, it suggests a calculation involving these numbers. 3. **Hypothesis:** Check if the operation is multiplication or division involving these numbers. 4. **Testing multiplication:** Calculate $624 \times 2 = 1248$ which is not 248. 5. **Testing division:** Calculate $\frac{624}{2} = 312$ which is not 248. 6. **Testing subtraction from 1000:** Calculate $1000 - 624 = 376$ not 248. 7. **Testing subtraction from 1000 after multiplication:** Calculate $1000 - (2 \times 376) = 1000 - 752 = 248$. 8. **Check if 376 is related to 624 and 2:** Calculate $\frac{624}{2} = 312$ no. 9. **Try $1000 - (2 \times 376) = 248$ suggests 376 is a key number. Let's check if $624 - 376 = 248$. 10. **Yes, $624 - 376 = 248$**. 11. **Conclusion:** The operation is $1000 - (2 \times 376) = 248$ and $624 - 376 = 248$. Since the problem is ambiguous, the most straightforward interpretation is that the number 248 is the result of subtracting 376 from 624. **Final answer:** $$248 = 624 - 376$$
