There are many hymns attributed to Lord Ganesha. One of them is Sankatamochana Ganesha Stotram sung by Sage Nārada. The following is an excerpt from the Nārada Purāṇa .
In the hymn, twelve names of Ganesha are said. They are:
प्रथमं वक्रतुन्डम् च एकदन्तं द्वितीयकं |
तृतीयं कृष्णपिङ्गाक्षं गजवक्त्रं चतुर्थकम्||
Firstly, as the one with the twisted trunk. Secondly, as the one with the single tusk. Thirdly, as the one with the fawn colored eyes. Fourthly, as the one with the elephants mouth,
लंबोदरं पञ्चमं च षष्ठं विकटमेव च |
सप्तमं विघ्नराजं च धूम्रवर्णं तथा अष्टमम्||
Fifthly, as the pot-bellied one, Sixthly, as the monstrous one, Seventhly, as the king of obstacles, Eighthly, as the smoke colored one.
नवमं भालचन्द्रं च दशमं तु विनायकं |
एकादशं गणपतिं द्वादशम् तु गजाननं ||
Ninethly, as the moon crested one, Tenthly, as the remover of hindrances, Eleventhly, as the Lord of the hordes, Twelfthly, as the one with the elephants face.
The above said are the twelve names of Lord Ganesha as said by sage Nārada in Nārada purāṇa . Also there is a representation of numbers from 1 to 12. The number zero (0) is called shoonya(nothing) in sanskrit.
