This is HP’s first desktop calculator, and it cost the same amount in the late 1960s as it does now.
This programmable calculator has several basic operations as well as some more advanced capabilities that allow you to execute more complex calculations.
It has a reputation for being one of the world’s greatest early scientific calculators.
Grillet portable Calculator ($155, 000)
The most costly calculator is the world’s first portable calculator, which was created in the 17th century. Rene Grillet de Roven, a Parisian, created the measuring instrument in 1763 with a 32cm x 15cm piece of wood. It is built according to Napier’s logarithm.
It’s one of only four known specimens of this design, and the only one in private hands, which adds to collectors’ interest.
As a result, we believe the high estimate of £100,000 ($155,098) is well justified ahead of its sale on October 10 at Christie’s Travel, Science, and Natural History auction.
HP Hewlett-Packard 9100a Calculator ($4,900)
The Hewlett-Packard 9100A (hp 9100A) was a pioneering programmable calculator (or computer) that debuted in 1968.
“If we had named it a computer, it would have been rejected by our clients’ computer experts because it didn’t look like an IBM,” Bill Hewlett explained, “because it didn’t look like an IBM.” As a result, we chose to name it a calculator, and all of the gibberish vanished.
One of the earliest recorded uses of the word “personal computer” (as of 2000) is in a 1968 Science magazine ad for the 9100A.
Wolfram Mathematica 9 Calculator ($2500)
Mathematica isn’t a stand-alone calculator. It’s a sophisticated computational application that’s often used as a virtual calculator. The basic version is available in single and corporate editions, with prices ranging from $2495 to $6995.
Wolfram Mathematica is a software system with built-in libraries for machine learning, statistics, symbolic computation, manipulating matrices, plotting functions and various types of data, implementation of algorithms, creation of user interfaces, and interfacing with programs written in other programming languages that allow machine learning, statistics, symbolic computation, manipulating matrices, plotting functions and various types of data, implementation of algorithms, creation of user interfaces, and interfacing with programs written in other programming languages.
It was created by Wolfram Research in Champaign, Illinois, and was imagined by Stephen Wolfram. Mathematica uses the Wolfram Language as its programming language.
HP 32Sii Scientific Calculator ($700)
Hewlett-Packard debuted the HP-32S, a programmable RPN Scientific Calculator, in 1988 and it was discontinued in 1991.
It carried on the legacy of HP’s programmable RPN Scientific Calculator, the HP-15C.
However, because some capabilities of the HP-15C were eliminated (matrix computations) and others were limited in capability (complex calculations), it is more accurate to state that the HP-32S extended upon the HP-34C to some extent. Complex math, statistics, probability, and other functions were supported.
HP32Sii is a rare model these days, as it was discontinued in 2002 after being introduced in 1991. At a price of $699.99, it is rarely seen on Alibaba or Amazon. HP32Sii has been shown to be an effective tool for doing difficult calculations.
Calculators are often equipped to tackle basic computation issues, although scientific calculators that assist users with trigonometric and statistical calculations are also available. The top twenty most costly calculators are shown below.
