Hidden expression is a way of expressing mathematical formulas that can be hidden in the text without affecting the reading experience of the text. This expression is widely used in scientific and technological fields and academic research. Below we will introduce hidden expressions from the following aspects.

1. What is a hidden expression?

Hidden expressions refer to using specific symbols to wrap mathematical formulas in text so that they are not displayed in the text, but can be displayed through operations such as mouse hovering or clicking. This expression not only ensures the readability of the text, but also facilitates the insertion of mathematical formulas.

2. Advantages of hidden expressions

Compared with the traditional way of displaying mathematical formulas in-line or centered, hidden expressions have the following advantages:

(1) Beautiful: Hidden expressions will not disrupt text layout and make the article more beautiful.

(2) Easy to read: Hidden expressions will not interfere with the reading experience of the article, allowing readers to focus more on the content of the article.

(3) Flexible: Hidden expressions can be inserted, deleted or modified at any time, which is very flexible.

3. How to use hidden expressions?

Using hidden expressions requires mastering some basic grammatical rules. Taking LaTeX as an example, we can use the "$" symbol to wrap mathematical formulas, as follows:

$y = ax^2 + bx + c$

This way Hide mathematical formulas in text. It will appear when the mouse is hovered or clicked.

4. Application scenarios of hidden expressions

Hidden expressions have been widely used in the scientific and technological fields and academic research. For example, when inserting mathematical formulas into papers, reports, blogs, etc., using hidden expressions can make the article more beautiful and easier to read. In addition, when writing code, you can also use hidden expressions to express some complex calculation formulas.

Hidden expression is a very practical way to express mathematical formulas. It is not only beautiful and easy to read, but also flexible and convenient. We believe that in the future technological development, hidden expressions will have more application scenarios.
