Indian mathematicians formalized zero as both numeral and placeholder. Brahmagupta codified arithmetic rules with zero in the 7th century. The concept traveled through Arabic scholarship to Europe. It revolutionized positional notation; algebra; and calculus.
Hardware covers the tangible components—CPU; memory modules; storage drives; motherboard; and peripherals. Software instructs hardware via operating systems and applications. Both layers interact through device drivers and firmware. Reliable performance depends on harmony across these parts.
Pascal’s 17th-century Pascaline used geared wheels to add and subtract. It mechanized arithmetic long before programmable engines. Babbage later sketched general-purpose designs; Aiken built electromechanical computers. Each step advanced computing from manual to automated calculation.
Volume(sphere) = (4/3)πr³ and Volume(cone) = (1/3)πr²h. Setting them equal gives (4/3)πr³ = (1/3)πr²h. Cancel common factors to obtain 4r = h. Hence the cone’s height must be four times the radius.
Initial count fixes c = 80. Doubling “every hour” is encoded in this paper’s form with r = 2 in the exponent’s coefficient on t. Thus A(t) matches 80·2^{2t} under the given parameterization. The keyed option aligns with that setup.
