What is a calculator that does not have a storage function? 5

This sentence is actually "a calculator that can be brought with normal data, and a calculator with a data entrainment function is not allowed." "I say this to prevent cheating.

1. You can bring the calculator with the white shell and green keys.

2. The so-called storage function refers to calculators such as mobile phones and electronic dictionaries, which can store some information. The names of "calculators" on the market are basically professional calculators, which can only be used for scientific calculations and cannot store information. (M and independent storage unit ABC and so on can only store numbers, not counting with storage function).

3. The teacher will not check, and has never heard of someone bringing a calculator, and the calculator does not meet the requirements.

The most common type of arithmetic calculator is the most common one, which can do four operations.

You can memorize a number, which is the "MR" key, or you can know it clearly with the "MC" key.

Scientific calculators.

There is a storage function, which can generally memorize the calculation formula of 225 steps, some can remember more information, and can assign values to more than a dozen variables. But some machines are turned off and turned on, and the data is still there, and some will be emptied. Generally, if you change the battery, you will lose the storage information.

Most program calculators have a flash memory function, and shutting down or even changing the battery will save data, but some older models don't.

Generally, it is enough to buy an ordinary scientific calculator, many old engineers use Sharp 506h, a machine with only basic scientific calculator functions, you go to the Internet to search, very quaint 80s design. The old men called this a "function machine".

This kind of exam can be used.

The calculator shown in the diagram is not a calculator with a storage function.

Function calculators (also known as "scientific calculators") are the general term for a class of calculators with the function of numerical calculation of elementary functions, and are the most commonly used type of calculators.

Due to the different manufacturers, models, etc., it has different calculation functions, the general level is equipped with elementary function calculation functions and statistics, regression analysis and other functions, and the more advanced ones are equipped with numerical calculus, numerical summation or product, base conversion and bit operation, scientific constants, unit conversion, matrices, vectors, solving equations (groups), solving inequalities, probability distributions, relationship proofs and other functions.

It is often used for general numerical function calculation in science and engineering or practical engineering, and does not have the functions of programming, text storage, high-precision operation and symbolic operation, drawing, etc.

The composition of the calculator:

1. The calculator is generally composed of combinators, controllers, memory, keyboards, displays, power supplies and some optional peripherals and electronic accessories, through manual or mechanical equipment. The combinator and controller of the low-grade calculator are simple serial operations by digital logic circuits, and their random access memory is only.

One or two units for cumulative storage.

2. The high-end calculator implements various complex calculation programs by microprocessor and read-only memory, and has more random memory units to store input programs and data. The keyboard is the input part of the calculator, which is generally contact or sensor.

3. In order to reduce the size of the calculator, one key often has a variety of functions. The display is the output part of a calculator, such as a light-emitting diode display or a liquid crystal display. integrated circuits (see Complementary Metal-Oxide-Semiconductor Integrated Circuits) with an automatic power-off circuit with timed non-operation inside.

4. The peripheral equipment that can be used for the calculator includes micro printers, cassette tape drives and magnetic card machines.

If the landlord is about to carry the calculator shown in the picture, yes.

A calculator with a storage function generally refers to a calculator that can store data and data, mainly to prevent candidates from carrying private goods, similar to making cheat sheets. As long as the landlord carries a general function and quiet calculator rather than a calculator with special purposes, such as modeling and drawing calculators, financial calculators, etc., it can be used under normal circumstances.

It's easy to understand.,It's allowed to use a relatively simple calculator.,Calculators with the following characteristics can't be used:

If an outer protective sleeve is added to avoid entrainment;

Shape it upright to prevent your calculations from being seen by people behind or next to you. Let's use a plate.

If you can store content or formulas, avoid storing "cheat sheets" on your computer.

For exams, of course, it is not allowed.

If you have passed the accounting exam, you can do it.

Hello, did you bring in the exam?

Use the calculator's storage functions as follows:

1. First, enter the formula you want to calculate in the calculator, e.g. 7 Bang Bang Spine 8 15.

2. After the calculation result is displayed, it will be displayed on the screen, then press the shift key, then press the STO key, and then press the A key to the top of the red capital letter. This process saves the results on your computer.

3. Then press the alpha button, then press the A button. The result here is equal to the result stored in the previous step. This process is a copy of the previous step, and the result is a 3 18.

Calculators don't have a memory function, and it's not the same as calculators don't have a storage function.

Some standard calculators have a digital storage function, which includes four buttons: MRC, M-, M+, and MU.

After typing the number, press MS to read the number into memory, and then no matter how many steps are performed, you only need to press MR once to read the previously stored number, press MC to remove the number from memory, or press twice to calculate the interest rate, 2000 [mu] 20% = 2000 (1-20%) = 2500, 2000 [mu] [ 20% = 2000 (1 + 20%) = .

If the calculator has "Ctrl+M+", it means that the calculator has a storage function, and if it has an M+ function, it means that the calculator has a storage function.

Calculators without storage function refer to scientific calculators, which can perform operations such as squares, logarithms, exponents, and multiplications, which are of great help to mathematics work or number sidebanding majors.

A calculator with a storage function can store some data, this kind of calculator can calculate some complex data, and it can also measure some data, and not only that, it can also store data.

The calculator we use in our daily life is a simple calculator, which can only do addition, subtraction, multiplication and division operations.

Commonly used keys in simple calculators include clock, which is an alarm button, and you can press the clock button on the calculator to announce the time in real time, in addition to setting an alarm clock. If there is no voice announcement function on the calculator, then there is no clock button on the calculator.

There is no clock button in the scientific calculator, and it cannot broadcast the time, let alone set an alarm. However, the scientific calculator can calculate super large numbers, and also has functions such as overflow indication and error indication, which can better help users deal with numbers.

How to use the storage function of the calculator:

1. Start by entering the formula you want to calculate in the calculator, such as 7 8 15.

2. Once the calculation result is displayed, it will be displayed on the screen, then press the Shift button, then press STO, and then press A to the top red capital letter. This process saves the fruit in your computer.

3. Then press the alpha button, then press the A button. The result here is equal to the result stored in the previous step. This process is a result of the previous step. a＋3＝18。
