The algorithm handles this partially or ambiguously because Step 3 explicitly specifies adding “the two digits.” It lacks instructions for processing the remaining leftmost columns where the 3-digit number has no digits left.

class 9 maths ganita manjari part 2 chapter 11 question answer
The written algorithm does not handle this situation cleanly. Step 3 requires adding “the two digits and the current value of carry.” In the thousands and ten-thousands columns, the 3-digit number has no digit. Unless we formally specify padding the shorter number with leading zeros or treating missing digits as zero, a strict literal execution halts because one digit is missing in those columns.
