Question: Which system of numerals originated in the country where Flora Steiger-Crawford was born?

The Hindu-Arabic numerals, a positional numeral system, originated in India and was later transmitted to the West through the Arabs. Classical India refers to the period when much of the Indian subcontinent was reunited under the Gupta Empire (c. 320–550 CE). This period has been called the Golden Age of India and was marked by extensive achievements in science, technology, engineering, art, dialectic, literature, logic, mathematics, astronomy, religion, and philosophy that crystallized the elements of what is generally known as Hindu culture. Early Hindu numerals had only nine symbols, until 600 to 800 CE, when a symbol for zero was developed for the numeral system. The peace and prosperity created under leadership of Guptas enabled the pursuit of scientific and artistic endeavors in India. <SEP> the name "" was taken from the niger river running through the country. this name was coined in the late 19th century by british journalist flora shaw, who later married lord lugard, a british colonial administrator. the origin of the name "niger", which originally applied only to the middle reaches of the niger river, is uncertain. the word is likely an alteration of the tuareg name "egerew n-igerewen" used by inhabitants along the middle reaches of the river around timbuktu prior to 19th-century european colonialism. <SEP> Mumbai Bombay Megacity Mumbai Top to bottom: Cuffe Parade skyline, the Gateway of India (L), Taj Mahal Palace Hotel (R), Chhatrapati Shivaji Terminus and the Bandra -- Worli Sea Link.

In 1923, she became the first woman to graduate in architecture from the Federal Institute of Technology in Zurich where she studied under Karl Coelestin Moser. After working with Pfleghard & Haefeli in Zurich, she married Rudolf Steiger in 1924 and established her own firm with him in Riehen, moving to Zurich the following year. Their first project, the Sandreuter House in Riehen (1924), is considered to be the first Modernist house in Switzerland. Steiger-Crawford went on to design individual houses while developing modern furniture, including a stackable metal chair for the Zett House in Zurich (1932). In 1930, she turned to sculpture, terminating her architectural activities in 1938. From 1938, she was a member of the Swiss Association of Female Artists and Sculptors.
