Win7 system has built-in "math input panel" tool, which few people know. This function makes the use of mathematical formulas more convenient and simple. People are used to calling the formula editor in Word for input, but the operation steps are a bit cumbersome. In order to improve the efficiency of writing mathematical formulas, you can try keeping a diary, which is simple to operate. Interested students learn the operation together.

The specific method is as follows:

1, Windows Diary is a very interesting gadget that comes with win7. You can keep a diary and doodle, but it's hidden.

2. First, you need to run Windows Journal. You can click "Run" in the start menu and enter "Diary" to open it. You can also click "Windows Journal" in the "TabletPC" column in the start menu to run it.

3. Then in the Windows diary window, use the mouse to enter the mathematical formula to be handwritten. After the input is completed, use the selection tool to select the mathematical formula just written. It should be noted that all written mathematical formulas need to be included in the selection range for complete selection.

4. Then run the math input panel and drag the selected math formula in the Windows Journal window to the input area of the math input panel, so that the math formula can be recognized and displayed in the math input panel. Of course, sometimes, the mathematical input panel inevitably has shortcomings in recognition and display, and sometimes there will be upper display errors. At this point, you can use the selection and correction functions of the math input panel.

5. Click "Select and Correct" on the right side of the math input panel, and select the wrong part in the input area to pop up the corresponding correction option, select the correct display content from it, and re-enter the content to successfully correct the formula display error, which is very convenient.

6. By clicking "Insert" at the bottom of the mathematical input panel, you can also put the corrected correct mathematical expression into the program of the recognized mathematical expression.

7. It is worth mentioning that the mathematical input panel also has records of querying and writing mathematical formulas. Click "History" to display the correctly written mathematical formula. When the user needs to use a formula, click the formula in the history to display and use it in the math input panel.

Mathematics is a particularly important subject. If you don't know how to write mathematical formulas in win7 system, you can use the diary function, which is simple and convenient to operate! I hope I can help you.
