The following is a detailed tutorial:
I. Input of scores
If the solution is based on the definition domain, then the input of the score is still very simple. For example, if we want to input three-quarters of the number, just press the shortcut key "Ctrl+F9" at the corresponding position, and an airspace (a pair of braces) will be generated. Place the mouse in braces, enter "eq f (3,4)", and then right-click "Switching Domain Code" in the pop-up menu to get three-quarters of the standard score, as shown in figure 1. Other scores can be imitated. Don't worry about the horizontal line in the score. It automatically adjusts the length according to the length of the numerator and denominator. It should be noted that the domain code must be entered in English half-width state. In addition, the braces can't be entered manually, but can only be completed by shortcut keys.
WPS switches domain codes to get the score effect.
Second, the score with the root sign.
Let's start with a simple digital input, such as three twos. Or press "Ctrl+F9" shortcut key first, then enter the domain code "eq (3 3,2)" in braces, select the number "3" in the code to reduce its font size, and then press the "Switch Domain Code" command in the right-click menu, and you can get the root number three times and twice.
Enter the special domain code in WPS.
Obviously, if you want to get the quadratic root, you just need to change the number "3" to "2" in the code. But usually our habit is to ignore the number "2" in the quadratic root, so we can also omit the first number in the domain code directly and just write the code "eq (,2)".
As for the fraction with the root sign, it's very simple. Combine the score with the radical code and change it in the corresponding position. Therefore, the domain code of two-thirds root numbers should be "eq f((3 (3,5), 2)". After pressing "switch domain code", the effect is ok.
Third, input vector symbols.
The vector symbol is the arrow symbol above the English letters. This requirement can also be easily realized by domain functions.
Enter the domain code "eq o(→, a)" with braces, in which the arrow symbol can be realized by the method of "insert → symbol". If we click the "switch domain code" command in the right-click menu at this time, you will find that the result is only the overlap of arrows and letters, which is not what we want. So, how do you move the arrow up?
Select the arrow in the field code, right-click, and then click Font in the pop-up menu to open the Font dialog box. Click the Character Spacing tab, then click the Position drop-down list, select Ascend, and use the following Point Value spinner button to set the elevation value to "5 points", as shown in Figure 3.
After confirmation, the arrow symbol can be moved up by 5 points to move it above the character. Now, select the domain code again, and then click the "Switch Domain Code" command, and you can get the expected effect.
