History of Place-Value System in India

All three statements are correct. Statement 1 is true because the Mankani copperplate inscription of Taralasvamin (AD 595–596) features the earliest known epigraphical entry using a decimal place-value arrangement in India. Statement 2 is correct as the system spread extensively during the 9th century CE, appearing widely across Rastrakuta, Pratihara, and Pala imperial inscriptions. Statement 3 is correct because Hindu-Buddhist maritime expansion carried the mathematical notation system rapidly to Southeast Asia, appearing in early 7th-century Sanskrit epigraphs in Cambodia and Sumatra.
