To write 150 crore in numerical form, you would write it as "150,00,00,000" in the Indian numbering system. In this system, commas are placed after every two digits starting from the right. Each comma denotes a place value of two decimal places, similar to how commas are used in the Western numbering system to separate thousands, millions, etc.
In common with the other Mesoamerican civilizations, the Maya used a base 20 (vigesimal) and base 5 numbering system (see Maya numerals). Also, the preclassic Maya and their neighbors independently developed the concept of zero by 36 BC
N (or nulla) is a very rare way to write a zero. The standard Roman numbering system does not include a zero or null value. Even if it did, the structure you are proposing is incorrect.
