Calculators
A calculator is a hand-held inexpensive electronic device used to perform the operations of arithmetic. The simplest calculators can only do addition, subtraction, multiplication, and division, while scientific calculators can handle exponential operations, and trigonometric and logarithmic functions.

What can you use a a refinance calculator for?
A mortgage calculator can be used to find out if it is worth it to refinance your monthly payments, if it will lower your payments and if you would save on interest and fees. By entering your data you can decide if it is worth it to refinance your home mortgage.
Are refinance calculators accurate?
Refinance calculators are a great tool when estimating home loan and payment rates. I would not suggest they are 100% accurate, but can be useful in giving someone a close approximation as to what their payment will be at a specific interest rate.

How do you make a shape on a graphing calculator?
In order to make most (recognisable) shapes on a graphing calculator, you will need to use at least 2 graphs mapped onto the same set of axes. For example, to make a heart, you havce 2 equations - Y1 and Y2 where:
Y1=(3/2)x^(2/3)+√(20-x²)-3
Y2=(3/2)x^(2/3)-√(20-x²)-3
This will give you what looks very much like a Valentine heart shape (changing the 3/2 at the start of each part to a 2 may give a taller heart, but it is thinner and IMO doesn't look as nice - choosing a coefficient between about 1.3 and 2 would give you the best Heart shape)
There are various other shapes that can be made too, but I'm not sure how to do them off the top of my head
How do calculators calculate logarithms?
As far as I am aware there is no formula as such to calculate log. The definition of a log is n = Blog n , where n is the number being logged and B is the base to which it is being logged. This means, log n is the power to which B must be raised to give n.
It's not difficult to estimate once you decide what B is. If you choose base 10, which is what we count in usually, the first number in the log is the highest power of 10 which is lower than the number. If the number is 5000 then the 1st number in the log will be 3, as 103 = 1000 . log 5000 will be more than 3, less than 4.
You can work out approximate values for log n by plotting a graph on ordinary graph paper. If you plot 0 to 10 across and 0 to 1 up the side, then put in the two points properly known (where n=1, log1=0 and for n=10, log10=1). Easily memorable are log of 2, 4, annd 8 which are very close to 0.3, 0.6 and 0.9, but those came straight out of my calculator.
ANSWER:
There are several ways to calculate logarithms. Euler could calculate logarithms using a binary search and the geometric mean. There is another way to calculate the log using the natural logarithm, base e. I developed my own method using squares, and there is a link provided.
Where was the calculator first launched?
The first calculator was never launched, because it was in fact a mechanical calculator.

How do you get to preloaded games on a graphing calculator?
If they are "preloaded" you have them already installed.
Consult your manual.
Go to the website of the manufacturer and ask there.
Where can I buy a ti 84 calculator?
The TI 84 calculator is a Texas Instruments graphing calculator. These are widely available at stores such as Walmart, Office Depot and Best Buy. They are also available online from Amazon or eBay.
Find square footage of odd shape?
The answer depends on the nature of the complex shape. Some complex shapes can be decomposed into smaller shapes whose areas can be determined using standard formulae. It is then simply a question of adding the parts together. For more complicated shapes, there are essentially two options: you can either use uniform laminae and mass or estimate the area using grids.
Uniform Lamina: Copy the shape onto a sheet (lamina) of material with uniform density. Cut the shape out carefully and measure its mass (or weight). Do the same for a unit square of the lamina. Then, because the lamina is of uniform density, the ratio of the two areas is the same as the ratio of the two masses. That is: Area of Shape/Area of Unit Square = Mass of Shape/Mass of Unit Square. Rearranging, and noting that the area of the Unit Square is, by definition, = 1 sq unit Area of Shape = Mass of Shape/Mass of Unit Square.
Grid Method: Copy the shape onto a grid, where each grid square has an area of G square units. Count the number of squares that are fully or mostly inside the shape. Call this number W (for whole). Count the number of squares that are approximately half inside the shape and call this number H (for half). Ignore any square that are less than half in the shape. Then a reasonable estimate of the area of the shape is G*[W + H/2] square units. There is some arbitrariness about "mostly inside"Â and "approximately half"Â but there is no way around that. You will get more accurate results with finer grids, but they will also require much more effort in terms of counting the grid squares.
How do you calculate an antilog on a casio fx-115ES?
Below the <X-1> key, below the <MODE/SETUP> key, you will find log. You have to press the <SHIFT> key (upper left-most key) and then <log> key (which accesses the <10x> antilog function); then enter the number on which you want to perfom antilog; then press the <Ans> key
Where was the first calculator invented?
The first calculator dates back to 2700 BC with the invention of the Abacus, invented in Mesopotamia.
In the 1940's and 1950's, the first mainframe computers were invented, which led towards the hand-held calculators we know today.
In the mid-1960's, desktop calculators were coming to fruition, and in 1970, the first "Pocket" calculator was invented in Japan by Sanyo, called the ICC 0081.
What does the capital letter E mean at the end of a number on a calculator?
It means Error. If you try to divide a number by 0 it should give you the E. Also if you try to multiply numbers that will give a larger number than the calculator allows. I believe exponential calculators fix this by giving you a exponential answer.
What are the advantages and disadvantages of calculators?
Advantadges: * They make it easier to do math problems. * You don't have to go back and check because they're reliable.
Disadvantadges: * People are becoming more and more reliant on them. As a result, they can't do as much math in their head.
* Students are getting lazier and just use their calculators instead of doing it the old fashioned way. Advantadges: * They make it easier to do math problems. * You don't have to go back and check because they're reliable.

Can you use a graphing calculator on a NY Regents Exam?
Graphing calculators are *required* for students taking the Algebra, Geometry, and Algebra II/Trig Regents exams. Schools may not require students to purchase their own graphing calculators for these courses: "Under no circumstances should students be charged for a calculator or otherwise required to purchase one in order to participate in an educational program."
http://www.emsc.nysed.gov/mgtserv/charging_for_calculators.shtml
Graphing calculators are specifically forbidden on the Earth Science, Living Environment, and Chemistry Regents exams. They are permitted on the Physics exam.
http://www.emsc.nysed.gov/osa/08-09memo/jun-aug-09/730/541-809.pdf
As required by the state, your graphing calculator has to have its memory cleared before you take the exam. Many schools have a program that will do this automatically, and will clear your calculator before you enter the exam room. Be sure to back up any data onto your computer before the exam.
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."
