Why is it beneficial to underline rules, formulas, and important statements in textbooks?

Underlining rules, formulas, and important statements in textbooks is beneficial because it creates a stronger impression. By highlighting key concepts, learners reinforce their understanding and retention of the information. Underlining helps to visually differentiate crucial elements from the surrounding text, which can enhance memory recall during study sessions or while reviewing material later. This technique effectively draws the reader's focus to significant points that they need to grasp and internalize, facilitating better comprehension of the subject matter.

While making a book look organized and simplifying note-taking might seem appealing, the primary purpose of underlining is to emphasize and imprint critical information in the reader’s mind, making it easier to locate and remember essential details quickly.
