Advantage of using ppt in teaching mathematics is 

PowerPoint presentations (PPTs) have become a popular digital tool in modern classrooms, including mathematics education. They support visual and structured learning by combining text, images, and animations.

Key Points

• Using PPT in mathematics facilitates an effective way of communication by allowing teachers to present concepts clearly and visually.
• It enables the use of diagrams, graphs, animations, and step-by-step problem-solving, which helps in breaking down complex topics.
• Visual aids and structured slides support the retention and recall of information.
• Through a well-designed presentation, mathematical procedures and relationships can be communicated in a logical sequence, reducing confusion. PPT also allows the integration of multimedia, which can further enhance engagement and understanding. 

Hint

•  Choosing to create your own design or use existing ones refers more to the aesthetic flexibility of PPT, which is a feature, not a direct educational advantage.
• Presenting outlines of information in a sequential manner is a general benefit of slide-based tools but does not specifically highlight its strength in facilitating communication, especially in the context of teaching abstract subjects like mathematics.
• Creating a huge gap between reality and perception is a negative effect and not an advantage. In fact, effective PPT use aims to reduce such gaps by making abstract concepts more accessible.

Hence, the correct answer is facilitates effective way of communication.
