How much did the first calculator cost?

Question

I need to do an internet scavenger hunt....how much did the first calculator cost?

Answer 1

I don't know about the very first one, but when I was in the 10th grade, I took trigonometry. For that I needed a "scientific" calculator. I finally talked my father into buying me one because there's no way to calculate trig functions quickly without one. He bought a Texas Instruments TI-50 which had the basic calculator functions on it plus a few algebraic and trig functions. By today's Casio deluxe standards, it was still pretty simple, but it was state of the art at the time. It was about as big as a cordless phone and cost $50 plus tax. That was in 1977.

Answer 2

By 1971, a large number of manufacturers were producing calculators with LED displays, using chips manufactured by TI or the newcomer Intel. Intel's offering was actually the forerunner of the series of microprocessors used in most PCs today. The early models were expensive, but as large numbers of companies saw the size of the potential market, there began one of the most spectacular price wars in the short history of high technology. In two years, the cost of these devices had dropped by an order of magnitude. By 1974 a four function calculator could be bought for $30 (or £30 - for some reason the transatlantic technology premium always seems to track the dollar/Sterling exchange rate). The following year prices had halved again, and school students suddenly were able to afford them.

That's the best I could find.

Answer 3

properly, i love such questions.. enable x denote pen and y denote calculator. Given 2 pens + 3 calculators = 650 and six pens +5 calculators = 1350 2x+ 3y= 650----------(a million) 6x+ 5y= 1350--------(2) Multiply through 3 throughout the time of (a million) 6x+9y= 1950---------(3) 6x+5y= 1350---------(2) (3) - (2) supplies 4y= six hundred hence y= six hundred/4= 100 and fifty Now placed y=100 and fifty in (a million) 2x+3y= 650 2x + 3(100 and fifty)=650 2x+ 450= 650 2x= 650-450 = 2 hundred the necessary answer is the cost of two pens and four calculators So, 2x+4y=? 2 hundred+six hundred= 800 hence the cost of two pens and four calculators is Rs.800/-

Answer 4

The very first "calculator" ever built was actually nothing more than what we would call an adding machine, because it could
only do the four basic math functions--add, subtract, multiply,
and divide. It was built in Philadelphia back in 1878, and took up
one whole city block, and stood two stories tall. It was extremely
expensive to build, especially 129 years ago--$240,000.00.

Answer 5

That question is impossible to answer unless you want to narrow it down. Various forms of caculators have been known to exist since around 300 BC.
