2. Insert a ready-made mathematical formula, mainly by using the existing mathematical formula for input, so as to achieve the purpose of inserting a complex mathematical formula. The main operation is to use the insert function in 20 10 version of word to insert complex mathematical formulas. As shown in the figure.
The second method is to edit the formula by yourself, so as to achieve the purpose of inputting complex mathematical formulas. The main way is to carry out the corresponding operation steps on the basis of the previous steps, so as to achieve the purpose of inserting complex formulas, as shown in the figure, which is the author's insertion method. As shown in the figure, this method can make the document display many complicated mathematical formula symbols, so as to achieve the purpose of inserting complicated mathematical formulas.
