There is 5 tons of steel laid down in a Nuclear Testing Ground, then the U.S drops 5 Nuclear Bombs on top of the steel producing 5 million scientific calculators. Only way to get that much power in a small device. Honestly, that's a no brainer ;).
How do you work percentages on a calculator?
If the number is a whole number, such as 2, for instance, that is 200%
Generally percents are decimals, so .6 would be 60%.
So on and so forth.
How do you cange the time on a Casio 1846 w 71 watch?
To change the time on a Casio 1846 W 71 watch, first, pull the crown (the knob on the side) out to the second position. This will allow you to adjust the hour and minute hands. Turn the crown to set the correct time, and then push it back in to complete the adjustment. Make sure to check AM/PM if your model differentiates between the two.
How do you use a calculator in a computer?
Go to the "Start" menu in the lower left corner. After you click it, go to "All Programs" at the very bottom of the menu. A big list should appear. Look for "Accessories." Once you find that, click on it, and find "Calculator" in the list it gives you.
I hope this is informative enough!
What information is needed in order to use a car value calculator?
You will need to know some basic information about the car that's value is in question. You will need to know the make, the model, the year, the milage, and the general condition of the vehicle. Also, you will need to know how you plan to sell the car, because you can often get more for a car if you sell it yourself than if you trade the car in at a dealership.
How do you play games on a TI-84 Plus Calculator?
If you don't have games already installed on the calculator, you need to install them. If you already have them on your calculator, you need to go to the PRGM button, and if it is not there, go to the APPS button. If it is not either place, go to 2nd, MEM (above either the plus sign or minus sign), Groups, and then press the right arrow key to end up at UNGROUP. Go down to the game that you put on your calculator and hit Enter. Then the game should install on your calculator. If you don't have the game installed on your calculator already, follow the directions below: First you download the game from a website, such as ticalc.org, read the readme if it came with one, and then you send it to your calculator. To send it to your calculator, you connect the calculator to your computer with a black cable that came with the calculator. Then you make sure the calculator is turned on, and right-click the files that you downloaded. Go to Send this file to TI device... and when the window opens, click Send. If you don't see Send this file to TI device... when you right-click the game, then you don't have TI Connect installed. Either download it from education.ti.com, or install it from the CD that came with the calculator. Questions, see education.ti.com.
What is the difference between casio fx 991es plus and casio fx 991es calculator?
The Casio FX-82ZA Plus is a replacement for the Casio FX-82ES+ which was developed in collaboration with the South African Educators for the South African syllabus. The FX-82ZA model appears to have all the features of the FX-82ES.
Because it can do everything a calculator can do and a lot more besides. There are too many reasons to list. Things like being able to do graphs, or being able to see the lists of figures, rather than one at a time, a wider range of functions, the ability to do formatting, the ability to print out results and the ability to do much more complex calculations. Those are just some, but there are many more.
The major difference between a calculator and a computer is?
This is so silly. A calculator is something that gives you answers to a math question (ex. 2+2=4), and a computer has the internet, a software to type, and games. Everything a calculator doesn't have.
Do you have to have a calculator to do algrebra?
Calculators are very useful for algebra since often numbers will have more than two or three decimals, but they are not crucially needed. It is usually possible to simply not calculate at all and just work with the values as they are. This might lead to final equations like x = (6/21 + lg 4)/3, though.
Can you use calculator in online exams?
That would probably depend on the exam - and the purpose of the exam. Check the rules for any specific exam you want to take.
For example, the CCNA exam (in computer networking) forbids the use of calculators; in fact, the testing-taking software won't let the student open additional programs (like a Windows calculator), and the exam is supervised. Actually this isn't exactly an "online" exam, since the entire exam is downloaded to the testing center machine before the date of the exam; but this may give you the general idea.
When was the first hand held calculator made?
Blaise Pascal, France, 1642: invented the mechanical calculator. William Seward Burroughs in 1885 in New York, USA, constructed his first adding machine; though it proved commercially impractical, he patented a practical model in 1892
How do you open calculator from command prompt on mac?
Here are the steps:
# Click 'Start' (the menu list will appear) # Choose 'Run...' (a small window appears on the lower left part of the screen) # Type the command, cmd (You will be redirected to a new window (DOS prompt) # Then, type the command, calc (the calculator window appears on screen)
How do you write mixed fractions on a TI 30X IIS calculator?
To enter mixed numbers, use addition. For example, to enter 23/4 enter
(2+3/4)
Use parenthesis around it so that the calculator knows that it is all part of one value.
What is the number of work hours in a year?

How much are graphing calculators?
A scientific calculator is a type of electronic calculator, usually but not always handheld, designed to calculate problems in science, engineering, and mathematics. They have almost completely replaced slide rules in almost all traditional applications, and are widely used in both education and professional settings.
In certain contexts such as higher education, scientific calculators have been superseded by graphing calculators, which offer a superset of scientific calculator functionality along with the ability to graph input data and write and store programs for the device. There is also some overlap with the financial calculator market.
Scientific calculators are used widely in any situation where quick access to certain mathematical functions is needed, especially those such as trigonometric functions that were once traditionally looked up in tables; they are also used in situations requiring back-of-the-envelope calculations of very large numbers, as in some aspects of astronomy, physics, and chemistry.
They are very often required for math classes from the junior high school level through college, and are generally either permitted or required on many standardized tests covering math and science subjects; as a result, many are sold into educational markets to cover this demand, and some high-end models include features making it easier to translate the problem on a textbook page into calculator input, from allowing explicit operator precedence using parentheses to providing a method for the user to enter an entire problem in as it is written on the page using simple formatting tools.
The first scientific calculator that included all of the basic features above was the programmable Hewlett-Packard HP-9100A,[1] released in 1968, though the Wang LOCI-2 and the Mathatronics Mathatron had some features later identified with scientific calculator designs. The HP-9100 series was built entirely from discrete transistor logic with no integrated circuits, and was one of the first uses of the CORDIC algorithm for trigonometric computation in a personal computing device, as well as the first calculator based on reverse Polish notation entry. HP became closely identified with RPN calculators from then on, and even today some of their high-end calculators (particularly the long-lived HP-12C financial calculator and the HP-48 series of graphing calculators) still offer RPN as their default input mode due to having garnered a very large following.
The HP-35, introduced on February 1, 1972, was Hewlett-Packard's first pocket calculator and the world's first handheld scientific calculator.[2] Like some of HP's desktop calculators it used reverse Polish notation. Introduced at US$395, the HP-35 was available from 1972 to 1975. HP continues to develop and market high-end scientific calculators, like the HP-35s and HP-49 series, which have been favored by scientists and engineers, in labs, offices, as well as in the field. In 1974, HP had the HP-65, which could be programmable.[3]
Texas Instruments, after the introduction of several units with scientific notation, came out with a handheld scientific calculator on January 15, 1974 in the form of the SR-50.[4] TI continues to be a major player in the calculator market, with their long-running TI-30 series being one of the most widely used scientific calculators in classrooms.
Casio and Sharp have also been major players, with Casio's FX series (beginning with the Casio FX-1 in 1972[5]) being a very common brand, used particularly in schools. Casio is also the #3[citation needed] player in the graphing calculator market, and was the first company to produce one (Casio fx-7000G).
