## Number System in Hindi Notes

Hindi’s number system is derived from the Indian numbering system, which represents numerals with a mix of regional and Sanskrit terminology. It’s crucial to remember that this numbering system could fluctuate slightly throughout Indian regions, and that these numbers are represented in official writing using the Devanagari alphabet. By combining digits and the proper place values in a similar manner, the system can handle even larger numbers.

संख्याओं को लिखने और संख्याओं के नामकरण को व्यवस्थित करने की प्रक्रिया को संख्या पद्धति कहते हैं। संख्या पद्धति में हम 0 से लेकर अनंत तक कि संख्याओं के बारे में पढ़ते और समझते हैं। संख्या पद्धति में संख्याओं को कितने वर्गों में बाँटा गया हैं यह जानकारी समझकर संख्याओं का उपयोग करना सीखते हैं। 0, 1, 2, 3, 4, 5, 6, 7, 8, 9…….. अनंत तक की सभी संख्याओं को हम संख्या पद्धति कहते हैं।
