History of the Calculator related to Education<br />By: John Chambless<br />
2.
Overview<br />In this presentation we will discuss the origin of the Calculator.<br />How the Calculator has evolved in today’s modern world.<br />Last , What will happened to the Calculator’s future?<br />
4.
The Abacus<br />The first calculator<br />Today it is still debated whether the Babylonians or the Chinese invented it.<br />Used before written numeral system invented.<br />Constructed from a wooden frame with beads sliding on wires. <br />Still used by some merchants, fishermen and clerks in Africa, Asia, and elsewhere.<br />

Slide Rule<br />Invented in 1622 by William Oughtred.<br />Allows multiplication and division operations to be carried out significantly faster.<br />People who sent the space shuttle Apollo to the moon used the slide rule for their calculations which was in 1961.<br />
10.
Calculating Clock<br />Invented in 1623 by Wihelm Schickard.<br />Known as the first mechanical calculator.<br />The calculator was made from cogs and gears which were normally used for clocks. <br />It was the size of a typewriter.<br />It could add, subtract, multiply, and divide to up to six-digit numbers.<br />
12.
Pascaline<br />Invented in 1642 by Blaise Pascal<br />Pascal invented it to reduce his father’s tax work load.<br />Used for taxes in France until 1799<br />
14.
Arithmometer<br />Invented in 1820 by Thomas de Colmar.<br />Was put into production in 1851.<br />It is was only mechanical calculator in commercial production for thirty years and sold all over the world from 1851 to 1878.<br />
16.
ANITA<br />Invented in 1961.<br />Was the world’s first all-electronic desktop calculator.<br />The ANITA had a full keyboard.<br />It used vacuum tubes and cold-cathode switching tubes in their logic circuits and nixie tubes for their numerical displays.<br />
18.
Busicom LE-120A “HANDY”<br />Was marketed in 1971 and made in Japan.<br />The first truly pocket-sized electronic calculator to use and LED display.<br />Even though it was the first pocket-sized calculator it had problems with the display and never went on sale.<br />
20.
Casio FX-7000G<br />The first graphing calculator released in 1985.<br />It came with 422 bytes of memory.<br />It could store up to ten programs in 10 program slots.<br />
22.
TI-89<br />The TI-89 was developed in 1998. <br />The TI-89 is a graphing calculator.<br />It allows symbolic manipulation of algebraic expressions which makes it capable to solve in of variables.<br />TI-89 has it’s own direct programmable language called TI-BASIC.<br />
23.
Conclusion<br />As you can see the history of calculators has been around all the way back to the Babylonians times.<br />The Calculator has played a major part of ancient history which influence the modern world.<br />Without the advancement of the calculator we could be using different methods to calculator complex equations which are done easily on today’s graphing calculators.<br />I believe future calculators will be able to mathematically calculate foreign currency.<br />Some how they will be able to access wireless to internet to get updated currency rates and mathematically calculate them for travelers.<br />
