Symbol set is applied in many fields of mathematics, and its basic set operations can be divided into three types: intersection, union and complement. However, some users and friends need to use MathType MathType when editing documents, but many people can quickly edit the symbols of intersection and union, but the symbols of complementary sets cannot be edited. To solve this problem, I would like to share with you how to input complement symbols in MathType.

The specific operation steps are as follows:

1. According to the usage habit, open the MathType formula editor and enter the formula editing interface. It doesn't matter whether you open it from word or double-click the desktop icon.

2. After opening MathType, if you want to edit in the work interface, put the cursor where you need to input supplementary symbols, move the mouse to MathType menu bar, and select Edit-Insert Symbol.

Click Edit-Insert Symbol.

3. In the pop-up Insert Symbol dialog box, select Description from the View drop-down menu, and other default settings need not be changed. Pull the scroll bar in the symbol panel below, find the supplementary symbol, and click Insert.

Pull the scroll bar in the symbol panel, find the complement symbol, and then click Insert.

4. Go back to the MathType editing interface and use a subscript template after the complement set. Click MathType toolbar template and select "superscript subscript template"-"subscript". Then enter a capital U in the subscript input box, thus entering a complete complement symbol.

Use subscript template after complement symbol.

The above content introduces the editing method of MathType's complement symbol for you. This clip is not complicated, but you need to find it carefully. Some people may just use the capital C letter and a footnote template to complete the input of complement symbols, but such symbols are not in conformity with the specifications and are also an unrecognized input method.
