Calculators

Unless your calculator has a key for it, the only method I know is awkward. Example : Take 24 and 114. Divide 114 ÷ 24. It gives 4.75. Subtract the integer part (4) to keep only the fraction part (0.75). Remultiply by 24. This gives 18. Do the same thing with the smallest number 24, and the new number 18. Divide 24 ÷ 18. It gives 1.33333333. Subtract the integer part (1) to keep only the fraction part (0.3333333). Remultiply by 18. This gives 12. Do the same thing with the smallest number 18, and the new number 12. Divide 18 ÷ 12. It gives 1.5. Subtract the integer part (1) to keep only the fraction part (0.5). Remultiply by 12. This gives 6. Do the same thing with the smallest number 12, and the new number 6. Divide 12 ÷ 6. It gives 2.0. When there is no fraction part left, the game is over, and the smallest number found is the GCF. So the answer is 6. Another example with 17 and 35. Divide 35 ÷ 17. It gives 2.05882352941. Subtract the integer part (2) to keep only the fraction part (0.05882352941). Remultiply by 17. This gives 1. Start again with the smallest number 17, and the new number 1. Divide 17 ÷ 1. It gives 17.0. There is no fraction part left, so the answer is the smallest number found, which is 1. When two numbers have no common factors, the answer will always be 1, since you can divide anything by 1.

It is the upwards arrow, it is the same symbol on the "6" key of your keyboard.

did u like the brand Casio 2328?

x^(-5/3) = 4

1/x^(5/3) = 4

x^(5/3) = 1/4

[x^(5/3)]^(3/5) = (1/4)^(3/5)

x = 1/4^(3/5) or,

x = 4^(-3/5)

Check:

x^(-5/3) = 4

[4^(-3/5)]^(-5/3) = 4 ?

4 ^(15/15) = 4 ?

4^1 = 4 ?

4 = 4

Clear Entry. So if you press the wrong number.. you can erase it without deleting your entire calculation.

== == The brand name was Bomar and it was in 1975 - they cost around $150 when they were first introduced

To be more of a convenience for people.

it is an electronic

The very first calculator ever used could be an abicus, an electronic calculator, or even your brain. The first calculator invented was the abacus.

Blaise Pascal invented the Pascaline, a type of calculater that was perfected when he was 30.

Not sure of the value for these models but if you find out I have a model 8-sdx calculator I would like to know valve of Thanks Bill

Abacus and Calculator and are same to the extent that both are used for doing calculations. One learnt how to use, these can help you to do calculations really fast. - Neeraj Sharma

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.

Each calculator has its own nomenclature for working with imaginary and complex numbers. Many scientific calculators allow you to just type -1 and hit the square root button and it will give you something like (0,1) or (1,∠90°). In the first example, the first number {the 0} represents the real part, and the second number {the 1} represents the imaginary part. This is what happens on the HP-48 and HP-50 in Rectangular mode. In the second example, the calculator is in Polar mode (degrees), rather than Rectangular. So the first number {1} is the magnitude, and the second {90°} is the angle, measured in a counterclockwise direction from the positive real axis. 90° points straight up and is purely imaginary.

If my calculator was in radians mode, rather than degrees, then it would show (1,∠1.57) 1.57 radians is pi/2 (to 2 decimal places), which is the same angle as 90°.

An earlier calculator that I had, you first had to put the calculator in complex mode, then you had to push an extra button to view the imaginary part of the answer.

If t is real then [1 to infinity) ie all real numbers from 1 to infinity, including 1 but not infinity. If t is in the complex plane then the domain of t^2+1 is also the complex plane.

Graphing calculators have the ability to see a visual representation of graphs and equations. Scientific calculators have less features and can only perform numerical mathematical equations. Graphing calculators cost around $90 while scientific calculators can be found for under $10.

Yes. It does not have to be an exact value.

Press "AC" then press and hold "RATE SET" the display turns off for about 2 seconds and then "EURO RATE" appears at top of screen, release "RATE SET" and type the value of your currency and press "RATE SET" again to confirm.

Note: On newest versions "RATE SET" is on the "%" key, on models with support for more currencies the keys can be "C1","C2","C3" and so, but the procedure is the same, repeat it with each key for each currency

(parentheses), {braces}, and [brackets]

EXAMPLE: for the nubmers 1 x 3 + 2 x 4

(1 x 3) + (2 x 4) = 3 + 8 = 11

1 x (3 + 2) x 4 = 1 x 5 x 4 = 20

I think you are thinking "natural logarithm" which is ln (lowercase L, not I). If you have taken calculus you learn about logarithm and its relationship with exponents
