Instructions and skills for using a calculator in Windows

1. ComputingTool It can help users complete data operations, which can be divided into "Standard Computing Tool And science Computing Tool "Two," Standard Computing Tool "Can complete simple arithmetic operations in daily work," Science Computing Tool Can complete more complex scientific operations, such as function operations, the calculation results cannot be directly saved, but the results are stored in the memory for paste to other applications Program And in other documents, its Use Methods and daily life Use Of Computing Tool You can click Computing Tool You can also enter the value on the keyboard. The following describes the commonly used "standards" in detail. Computing Tool "When processing general data, youUse "Standard Computing Tool "To meet work and life needs, click the" Start "button, select" All Programs "|" attachment "|" Computing Tool "Command to open" Computing Tool "Window. The default value is" standard ". Computing Tool ", As shown in figure 1.

Figure 1 StandardComputingTool

ComputingToolThe window includes the title bar, menu bar, number display area, and work area. The workspace consists of numeric buttons, operator buttons, storage buttons, and operation buttons.UseYou can first enter the first number of the formula to be calculated, the corresponding number is displayed in the number display area, then select the operator, then enter the second number, and finally select the "=" button, you can obtain the calculated value. When you enter the value on the keyboard, you can also press the Enter key to obtain the calculation result.

Below isComputingToolFunction introduction of each function key on the interface:

Backspace-delete one by one and roll back a number Ce-clear all. This indicates that after the input C-operation is completed, click the "c" button to clear the current operation result, the new computation Mc-Yes Mr-Yes read-store data MS-store the displayed number in the memory, original data in the memory is washed away. m +-YesComputingThe result is added with the number of stored data.

SQRT-square root

% Value after 1/100

1/X calculate the reciprocal

+/-Indicates positive and negative numbers.

When an error occurs during the numeric value input process, you can click the backspace key to delete the data one by one. to clear all data, click the "CE" button, after an operation is completed, click the "c" button to clear the current operation result. You can start a new operation when entering the operation again.

CalculatorYou can select "edit"-"copy" to paste the operation results elsewhere. You can also copy the lucky computing formula from other places, select "edit"-"Paste"ComputingTool.

When you are engaged in very professional scientific research work that requires complex scientific operations, you can choose "View"-"scientific type" to bring up "Science"ComputingTool"Window, as shown in figure 2.

Figure 2 ScienceComputingTool

In this window, the number base option, unit option, and some function operator numbers are added. The default value is decimal. When you change the number system, the optional unit options, number areas, and operator areas change accordingly.

During work, you may need to convert the number system. In this case, you can directly enter the value to be converted in the number display area, or use the calculation result to convert the value. Select the desired number system, the converted result is displayed in the number display area.

In addition, scienceComputingToolYou can perform some function operations,UseDetermine the unit of the operation, enter a value in the number area, select the function operator, and then click "=" to obtain the result.

2. Tips

A. Copy by pressing CTRL + C and CTRL + v.

B. Copy the formula 1024 + 512 + 256 + 128 + 64 + 32, and click "=" again.ComputingResult. Operator number"ComputingTool"Cannot be identified. When entering the formula, do not proceed in the calculator. When opening the calculator, open notepad and enter the formula in Notepad. after entering the formula, you can check whether there are any errors and then select, right-click and select "copy". Then, go to the calculator, open the "edit" menu, and select "Paste", OK!

C. Calculate the 9 power of 3: point 3, click "x ^ y", and then click 9, point =, and you will see the answer: 19683.

D. scientific and Standard algorithms are different. The calculation Law of the scientific interface of the calculator is based on the calculation law in our mathematics, that is, multiplication, division, and addition and subtraction. The calculation Law in the standard model is calculated in the order of input, input a number to calculate a number.

E. logical operation . Windows computing tool facilitates binary, octal, and decimal operations. And any hexadecimal conversion. If we want to convert the decimal number 69 to the binary number, we first use computing device enter 69, after completion, click the "binary" Single-choice button. calculation tool outputs the corresponding binary number. F.Statistical function.ComputingToolAnother feature is statistics. In scientific mode, press the "sta" button to bring up a statistical box, such:

To use the statistical function, we must first enter the statistical data. Assume that the raw data is 1, 2, 3, and 4. FirstComputingToolEnter 1 on the keyboard, and then press the "dat" button. The data will be input to the statistics box.To sum the statistical data, simply press the "sum" button and the result is output. Similarly, press the "Ave" button to get the average value, and press the "S" button to get the standard deviation.
