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.

How do you delete the history of a TI-84 calculator?
Press 2ND MEM (above +). Then select option 7, "Reset...". Select All RAM and press yes. This clear clear all memory except for your applications (such as your games).
If you want to clear absolutely everything, then instead if choosing All RAM, go over to ALL and choose All Memory... and press yes. This will delete EVERYTHING, so make sure this is what you want.

How does loan consilodation calculator work?
A loan calculator is either a computer program or an electronic calculator program that allows one to get a fairly accurate dollar amount of how much mortgage payments will be. The user must have some figures (or at least an idea) in order to input the information that the calculator will need. &&At the very least, the user will need to know, as closely as possible, how much money will need to be borrowed, and for how long the loan will be taken out for. In addition, the current interest rate for the specific type of loan must be known.
Why do letters equal numbers on your TI-83?
On a TI-83, letters are variables. You can use these variables to store numbers. The calculator also uses some of the variables for its storage. If you type A and press ENTER, you will probably get 0. This means that A is 0 (unless you changed it and made it something else.)
To change a variable, press the number you want the variable to be, then the arrow (STO>) and then the variable. For example,
25-->W
will make the variable W equal to 4. You can then use variables in your calculations. For example, if you make W equal to 4 and A equal to 5, then
WA + 3
will equal 23. (4 x 5 + 3)
Why is an abacus considered one of the first computers?
Because many people do not understand the differencebetween a manual calculation aid, a calculator, and an automatic computer.
A manual calculation aid is a manual device where the user needs to fully understand the calculation and how to manipulate the parts of the device to perform every step of the calculation. The user must perform every step of the calculation on the device himself by hand. An abacus is a manual calculation aid. A sliderule is also a manual calculation aid.
A calculator is a manual device where the user needs to understand the calculation he wants to perform but the device can perform the detailed steps itself. The user must request each step of the calculation from the device by hand.
A computer is an automatic device that once set up (programmed) will perform the calculation anytime it is needed, without any attention from the user and even if the user has no understanding of the problem at all (the designer of the program is the only one that had to understand the problem).

What is an early calculator that is still used today?
Before electronics were invented, Mathematicians used abacus's.
What exactly does an IRA calculator calculate and is it free?
An IRA calculator calculates dollar figures for your retirement and shows you how much you'll have depending on the amounts you contribute. There are free IRA calculators online but it is advised to talk to a professional about your plans.
How do you calculate percent on a calculator?
To find a percentage of a given number, multiply the number times the percentage expressed as a decimal : a percent equals 1/100 so 20% of a given number is that number times 0.20 (20/100).
Example :
To find 5% of 50.00, multiply 50.00 x 0.05 = 2.50 *
To find one number as a percent of another number, divide the value of the number by the other number, then multiply the decimal result by 100 and that is the percent (per 100) value.
Examples:
What percent of 52 is 13?
To find the value of 13 compared to 52, divide 13 by 52 = 0.25
Now the percentage is 100 times that or 25 percent.
And 13 is 25 percent of 52
What percent of 50 is 150?
Divide 150 by 50 and the answer is 3, multiply by 100 to yield 300%
150 is 300% of 50
--
* Some calculators have a percent function (usually marked with a '%' icon). If yours does, just follow the same procedure but you won't have to convert the 'percent number' into a decimal. In the same example above, you would input: 50 x 5 and then % - the calculator will automatically give you the answer (2.50).
How many KB are in the ti-84 plus calculator?
The TI-84 plus has 480 KB of FLASH ROM (for things like applications), and 24 KB of RAM (which is the active memory that the calculator is using, as well as basic variables and non-archived programs.)
What if your scientific calculator doesn't have brackets what should one use instead?
Use a double parentheses instead. EX. (( = [
Why calculator is called digital?
It's called digital due to the fact that ever since they've came out they've always had a digital disply instead of an analogue display.
Do most pocket calculators run on battery or solar power?
Most pocket calculators run on batteries because it is much more convenient to use in multiple places. However, some older calculators tend to run on solar power.
Is the TI 84 Plus Silver Edition a programmable calculator?
Yes. You can make programs directly on the calculator by pressing the PRGM button and selecting NEW. Or, you can download TI-Connect free at the ti site and use that program to make programs. Making programs on the computer is faster and allows you to save the programs as normal computer files. Then you use a cable to send the programs to you calculator. You can also send programs from your calculator to your computer. I would recommend programming on ti-connect and sending the files to your calculator, just make sure you don't exceed the memory, which shouldn't be that much of a problem on the silver edition.
What does the abbreviation c mean on a calculator if ce means clear entry?
One is clear, the other is clear everything. Use clear to just change the last number you put in. Clear everything to start all over again. The other keys relate to memory, of which your calculator seems to be able to store *one* number.
MC clears the memory (sets it to zero)..
MR recalls the memory (puts the number from memory into the display, so that you can add to it or whatever.
MS stores the number on the display into memory.
M+ adds the nmuber on the display to the number in memory
How do you write information into TI-84 calculator?
The TI-83 and TI-84-series calculators all have the ability to store programs written in TI-BASIC language. There is a built-in editor that can be accessed be pressing [PRGM][>][>], choosing 1. New, typing a program name (up to eight letters), and hitting [ENTER]. If you want to just type text instead of write a program, you can use the same editor. However, there are alternatives. The SourceCoder 2 tool lets you type out programs and documents on the internet, store them to .8xp files, and load them onto your calculator. You can use it at http://sc.cemetech.net . You can also use TI's Notefolio application, available from http://education.ti.com , or Document DE 6, at http://www.cemetech.net/projects/item.php?id=6 .
Why does my calculator keep giving the wrong answers?
You should first experiment with the calculator by having a friend or relative work a
few problems with it, and observe whether the accuracy of the results is a function
of the machine itself or of the operator. If the accuracy varies with different operators,
then we can conclude that your calculator shares a well-known, exhaustively-documented
characteristic with all machines designed for human input or control. The characteristic is
referred to by mathematicians, physicists, engineers, and stenographers by the official
SI acronym: GIGO. The acronym stands for the phrase "Garbage In, Garbage Out".
