You must use the Formula Editor to edit mathematical formulas. You can choose to use the formula editor provided with word or download the mathtype formula editor. Generally speaking, mathtype is used more when writing papers, because its function is more comprehensive and easier to use than the formula editor that comes with word.

In general, the mathtype option is automatically loaded in word. If you can't load it manually, you can also use the Insert-Object-MathType equation 6.0 to open the editing formula.

If the language of the paper needs editing, it is suggested to choose a professional retouching organization, such as an international scientific editor. The international scientific editing language retouching service mainly aims at the English manuscript language itself, including: spelling, grammatical errors, word accuracy, language habits, language logical relations and so on. Through revision and polishing, the publishing requirements are met, so that the user's manuscript will not be rejected because of language problems.

However, it should be noted that whether the article is published is closely related to the technical level, such as whether the viewpoint of the manuscript is novel, whether the research content has academic value and so on. For the technical level, the author still needs to grasp it himself. The language modification of the manuscript is only a prerequisite for the publication of the article, and it cannot be published after the language modification 100%.
