When adding 36424 and 2484 why is there no regrouping in the final step?

Answer 1

When adding 36424 and 2484, the operation is performed column by column, starting from the right. In the units column, 4 + 4 equals 8; in the tens column, 2 + 8 equals 10, which requires regrouping, but the next column, 4 + 4 + 1 (from the regrouping) equals 9. In the thousands column, 6 + 2 equals 8, and in the ten-thousands column, 3 remains unchanged. Since none of the final sums in each column exceed 9 after handling regrouping, there is no additional regrouping needed in the final step.
