"SHIFT" then "log" "DIGIT" "="

According to the Wikipedia article (see related link), Casio released the first graphing calculator in 1985.

It is a lot easier and faster to do your homework with a calculator.

When we have pockets.....

Depends on the school and the class. It's not only allowed but recommended in most science and engineering classes. If you're doing basic arithmetic lessons, the teacher may ban calculators.

in the example 17,18,19,20,21,22,23 you do the greek letter that looks similar to an E and it has a plus sign next to it so 17e+ 18E+ 19E+ 20E+ 21E+ 22E+ 23E+ if you have more then one occurance for that particular number you put 2nd then freq and input the number of times it occurs. if not then you finish by pressing the 2nd oxn-1 and then the square root button. and thats you standard deviation.

Place a towel on a flat surface. remove the back of the watch using a minurature screwdriver to remove the screws. Use a pair of tweezer to remover the spring holding in the battery. remove the old battery and replace it with a new one. Reeplace the spring to hold in the battery and then replace the back.

Depending on the complexity of the calculation, a calculator can provide accurate answers more quickly.

well i think the native dinosaurs did as they cant really calculate theirselves

It keeps track of all the numbers. Instead of calculators that only show what you're doing, it'll show what you did. For example, a regular computer calculator doesn't show you what you punch in. After you punch in 463 + 1, the second you press another number, that first number goes away, so you have to get a better calculator, or recalculate.

With a scientific calculator, you get a ride variety of buttons to help with different types of equations, and you have (on most) the ability to go back and check your question, and the ability to manipulate past numbers/signs.

In the math world, calculators perform operations one at a time, while computers can process a sequence of operations using provided instructions. A typical calculator requires many interactions to perform a computation, while a computer takes a set of instructions.

Since the advent of the information age, the term computer has been corrupted. It is most commonly used to refer to laptops and desktops, but can also describe any device with a digital processor and memory (such as a smart phone, a game console, or an MP3 player). These "computers" can perform mathematical computations, but are also used to process data (such as text, sound, and images) with logical operations. Strict mathematical computers lack this functionality.

Modern calculators, such as the TI-86, are implemented with calculator software that runs on "computer" hardware. These "computer" calculators only use their logic processing capabilities to present simple menus and dialogs to the user (unless special programs, like games, are installed and ran).

Well i had the same qustion first u press 2nd then you press the button that looks like this ^ then put your number inexample: 3 2nd ^ 78 it would be 4.272658682

Leibniz's calculator could multiply and divide as well as add and subtract. The pascaline calculator could only add and subtract.

The average solar calculator produces between 50 and 100 microwatts. A typical solar cell might produce 20 - 40 microamps at between 2 and 3V.

In practical terms, this is an incredibly small amount of electricity. You could easily generate that much electricity with a small hand generator.


Graphing calculators (which are never solar) use far more electricity (around 0.3 watts or 300,000 microwatts, which is aronud 4,000 times as much). This is why these calculators are never solar. To use solar cells they would need a solar panel 4,000 times bigger than the one on the non-graphing calculators, and that would be too big to fit on the calculator!

A retirement calculator is a calculator that calculates your retirement investments, funds, and lots more. It's a great resource to go to for all of your retiremt needs, as long as it involves calculating and math!

Pretty much everything we use is a computer, whether they're programmable or not. game controllers have computers. smartphones are computers. monitors have computers in them. TVs also do. Cars have them. and of course, calculators are computers also.

The slide rule very much simplified calculations of multiplication and division, especially were a ratio was to be used over and over. Edmund Gunter had already invented the Gunter scale, but it was clumsy and required dividers (the things like compasses, but with two sharp ends instead of one sharp end and a piece of pencil lead) to use. William Oughtred realized that two Gunter scales facing each other made it unnecessary to use the dividers. That realization was the invention of the slide rule.

The slide rule was developed to perform multiplication and division before calculators had been invented. a addition and subtraction

Graphing Calculators such as those created by Texas Instruments have graph maker features as a core function of the device. Children in High Schools across North America have used graphing calculators in their course work.

I am not 100% sure, but when you plug it in to your cable, it might charge. I am sorry if this does not work. Its just a guess

The first electronic calculator made was the Bell Punch ANITA MK7 made in England in 1961 and unique in the world untill 1964 when the US, Japan and Italy launched their own electronic calculators.

-- There may be a small hole in the back of the calculator labeled "reset". If so,

the calculator may be reset by carefully inserting the end of a straightened

paper-clip a slight distance into the hole, and pressing the tiny switch located

just inside the hole.

-- If such a reset switch is not provided, then the calculator is reset by momentarily

disconnecting the battery.

You are able to find out what monthly payment you will have to make. Simply put in loan amount the loan term in months or years, the interest rate and the start date of the loan. It will figure it up for you.

Advantages: * They make it easier to do math problems. * You don't have to go back and check because they're reliable. Disadvantages: * 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.
