📌 Explanation:
- These problems involve adding a multiple of 100 (like 100, 200, 300, etc.) to a 3-digit number.
- Since multiples of 100 only affect the hundreds place, you can add them easily by increasing the hundreds digit accordingly.
- For example:
- In
143 + 700, we add 7 hundreds to 1 hundred → 1+7 = 8 hundreds → 843.
- In
351 + 600, 3+6 = 9 hundreds → 951.
This helps build mental math skills and understanding of place value.
