In terms of the aliquot sum s(n), the deficiency is
n − s(n). Denoting by σ(n) the sum of divisors, the worth 2n − σ(n) is known as the number's deficiency.
For instance, consider the number 21. Its divisors are 1, 3, 7 and 21, and their sum is 32.
As a result of 32 is less than 42, the number 21 is deficient.
Moreover, all proper divisors of perfect numbers are deficient.
Varied symbol units are used to symbolize numbers in the Hindu-Arabic numeral system, most of which developed
from the Brahmi numerals. It's a descendant of the 3rd century BCE Brahmi script, which developed into the
Nagari script which in turn gave delivery to Devanagari and Nandinagari.
Devanagari Script referred to as 'Script of the divine
metropolis' got here from Devanagara or the 'city
of the god'. Deva means "heavenly or divine" and can be one of the phrases for a deity in Hinduism.
