Usually, when we need to input formulas, we always open Word first, and then call the formula editor for input, which is also troublesome. In fact, if you have used Windows 7, you can use a simpler method.

Press the Windows key on the keyboard to activate the "Start Search" box, and enter "Math" here (enter the "Math Input Panel" if it is a tablet computer). After pressing Enter, you will see the search results as shown in figure 1.

Select "Math Input Panel" and double-click to activate the built-in Math Input Panel component of Windows 7 (see Figure 2).

The next operation is much simpler. Use a handwriting input device or mouse to "write" the formula here (see Figure 3).

If there is an error in the formula editing process, you can click the "Select and Modify" button on the right first, and then drag and drop with the mouse to select the content to be modified. After releasing the mouse, the corresponding correction options will pop up, as shown in Figure 4. Needless to say how to change it. Click the "Insert" button in the lower right corner to enter the formula editing position of Word 2007.

When you need to exit the math input panel, right-click the program icon in the system tray area and select Exit from the shortcut menu. If you want to call the shortcut of formula input panel on the desktop, you can create a new shortcut with the path "%common program files% \ Microsoft shared \ ink \ mip.exe".
