From a Babylonian to a Hindu–Arabic Numeral
Write 
as a Hindu–Arabic numeral.
Step-by-Step
The place value of these three groups of numerals from left to right is
(60)², 60, 1
or 3600, 60, 1
The numeral in the group on the right has a value of 20 – 2, or 18. The numeral in the center group has a value of 10 + 1, or 11. The numeral on the left represents 1 + 1, or 2. Multiplying each group by its positional value gives
(2 × 60²) + (11 × 60) + (18 × 1)
= (2 × 3600) + (11 × 60) + (18 × 1)
= 7200 + 660 + 18
= 7878
