संख्या पद्धतियों की सूची

यहाँ संख्या पद्धतियों की सूची दी गयी है।

 स्थानीय प्रतीक 
ये सभी स्थानीय-मान पर आधारित हैं। इनमें से कुछ निम्नलिखित हैं-

 मानक (Standard) 
For the definition of standard positional numeral systems, see Non-standard positional numeral systems.

The common names are derived somewhat arbitrarily from Latin and Greek. For more information, see Hexadecimal#Etymology.

 गैर-स्थानीय अंकन (non-positional notation) 
बेबिलोन अंकों (Babylonian numerals) के पहले विकसित सभी संख्या पद्धतियाँ स्थानीय मान पर आधारित नहीं हैं।
