What times itself equals 117649?
You are asking for the square root of 117649 - which is 343 (which you could get by using the square root function on most calculators).
What year were calculators invented?
Texas Instruments invented the first calculator in 1967 I was looking to see how much they cost, as my dad gave me one around 1972 or 1973. I know, because I moved from that house that year. I was 7. We didn't have money, so I KNOW we didn't pay $135 for it! Anyway, I finally found this info on this Hewlett Packard website: http://h20331.www2.hp.com/Hpsub/cache/457008-0-0-225-121.html "When the HP-35 was introduced, there were 75 handheld calculators on the market from more than 20 manufacturers. All of these were four-function calculators and could only add, subtract, multiply and divide. From 1972 to 1976, four-function calculator prices fell 95 percent - plummeting from an average of $195 to just $9.95. Falling prices unseated a number of calculator brands."
Why do some calculators give different answers?
The difference in the working memory and significant digits, as well as the ability to handle mathematical operations in their proper order, can all cause one calculator to give a different answer than another. There are two main types of calculator: scientific and non-scientific. The non-scientific calculators are often simple calculators with few operations beyond arithmetic and memory operations (although they may have square roots). They are generally intended as a desktop calculator for use by people who have to add up lots of numbers. As such, they are very simple, and every operation (+-×÷) works on the last number displayed. This last displayed number could be the result of the last calculation. Thus, if you enter 1 + 2 × 3, when the multiply key is pressed, the calculation of 1 + 2 is done and the result of that is multiplied by the next number entered, that is, the result of 1 + 2 × 3 is 9 (since 1 + 2 = 3, and 3 × 3 = 9). These calculators do not have keys for parentheses, nor can they do exponential display. They are limited to something like ±0.0000001 to ±99,999,999, up to eight digits of display. Tthe more digits before the decimal point, the less that can be after it. In contrast, scientific calculators have many more functions (e,g. trigonometric, powers, logs) and know about proper mathematical order of operations. Thus with one of these types of calculators entering 1 + 2 × 3 will give the result of 7, since the multiply is done first and then the result of that is added to the 1 - it has calculated 1 + (2 × 3). They DO have keys for parentheses, as the proper order of doing operations may need to be overridden, eg (1 + 2) × 3 to get the same result as a simple, non-scientific calculator. Scientific calculators can also handle exponential numbers, so they can handle a much larger range of numbers (something like ±1 × 10^-99 to 9.9999999 × 10^99). There is a slight variation in the range that different scientific calculators can handle. This range depends on how much internal storage is allocated to store each floating point number. Most scientific calculators these days will display nine digits with a further two for the exponent, though some may only allow seven or eight digits, and some may allow ten or 11 digits, or possibly three digits for the exponent. Internally, they will usually work to one or two digits more than the displayed digits so that the result displayed is rounded properly. In summary, the difference in the working memory and significant digits, as well as the ability to handle mathematical operations in their proper order, can all cause one calculator to give a different answer than another.
What do the letters on a calculator mean?
I assume you mean graphing calculators. They are variables that you can store numbers to, like if you need to use it later on in a math problem. But they can't be used to figure out algebra equations. Say you have the equation n+1=2 and n+m=4. You would figure out the value of n, which is 1, and you could either remember it or store it to variable n. Then you could use the variable n in figuring out m instead of putting in 1. (4-n=m instead of 4-1=m)
What did the first calculator look like?
The first calculators were abacuses, and were often constructed as a wooden frame with beads sliding on wires. Abacuses were in use centuries before the written numerals system and are still used by some merchants, fishermen and clerks in China and elsewhere. In 1822 Charles Babbage proposed mechanical calculators; one called a difference engine, which was capable of holding and manipulating seven numbers of 31 decimal digits each; and another more advanced mechanical programmable computer called an analytical engine. None of these designs were completely built. In 1991 the London Science Museum followed Babbage's plans to build a working difference engine using the technology and materials available in the 19th century. The Olivetti Programma 101 was introduced in late 1965; it was a stored program machine which could read and write magnetic cards and displayed results on its built-in printer. Programming allowed conditional testing and programs could also be overlayed by reading from magnetic cards. The Olivetti Programma 101 has won many industrial design awards. The first handheld calculator was developed by Texas Instruments in 1967. It could add, multiply, subtract, and divide, and its output device was a paper tape. The first calculator was probably the abacus; this has several balls on wires and allows the operator (with some practice) to perform arithmatic.

Where could one find information on annuity calculators?
One can find information on annuity calculators by going to the place that provides them. Examples of places that provide annuity calculators would be Bankrate, Aviva and LifeAnnuities.
Could the first mechanical calculator add subtract mulitply and divide?
No, the very first mechanical calculators could only add and subtract. The first mechanical calculators were invented in 1623 by Wilhelm Schickard, followed by the Pascaline, invented in 1645 by Blaise Pascal. However, calculators that could multiply and divide were in use by the 19th century.
Why did early traders use the abacus?
They didn't have electronic calculators. Abacuses (or is it abaci? no clue... oh well...) are calculators, and they could use them to calculate things.
