  Indian numbers seem almost as messy as Roman numerals though. Verbally, the system seems to go thousand -> lakh -> crore -> thousand crore -> lakh crore, but then stop there, rarely extending to crore crore or inducting any farther. Meanwhile commas don't seem to follow the verbal convention - instead showing up every two digits even after a crore, so a thousand crore looks more like ten hundred crore, and a lakh crore looks more like ten hundred hundred crore.

    Crore is followed by 'Arab', not a thousand crore. The system also goes beyond 'Arab' but you won't normally encounter the higher terms.

    > Verbally, the system seems to go thousand -> lakh -> crore -> thousand crore -> lakh crore Most people don't deal in these numbers, beyond the crores. And in sciences, exponential notation is norm anyway. There's no way it is as messy as Roman numerals.
