They used hieroglyphs for the digits and were not positional . By 1770 BC, the Egyptians had a symbol for zero in accounting texts . The symbol nfr, meaning beautiful, was also used to indicate the base level in drawings of tombs and pyramids and distances were measured relative to the base line as being above or below this line . </P> <P> By the middle of the 2nd millennium BC, the Babylonian mathematics had a sophisticated sexagesimal positional numeral system . The lack of a positional value (or zero) was indicated by a space between sexagesimal numerals . By 300 BC, a punctuation symbol (two slanted wedges) was co-opted as a placeholder in the same Babylonian system . In a tablet unearthed at Kish (dating from about 700 BC), the scribe Bêl - bân - aplu wrote his zeros with three hooks, rather than two slanted wedges . </P>
