Notebook-Style Arithmetic
Each operation is done “by hand,” column by column:
- Addition/Subtraction: each column plus/minus carry or borrow.
- Multiplication: partial products, shifted and summed.
Decimal Verification
After each operation, we convert all numbers to decimal to verify correctness. This helps confirm you did the base-n steps properly.
