In a similar vein, Pāṇini (5th century BC) used the null (zero) operator in the Ashtadhyayi, an early example of an algebraic grammar for the Sanskrit language (also see Pingala).
Ring nada sane pateh, Panini (abad ka-5 SM) nganggen operator kosong (kosong) ring Ashtadhyayi, conto awal tata basa aljabar antuk basa Sanskerta (cingak taler Pingala).
