The Sulba Sutras, a collection of ancient Indian texts, played a crucial role in shaping the development of mathematics in Southeast Asia. These texts contained geometric and algebraic concepts that were later adopted and adapted by mathematicians in the region.

Indian mathematical knowledge was primarily transmitted to Southeast Asia through religious and cultural exchanges. Buddhist monks, Hindu traders, and scholars played a significant role in disseminating mathematical ideas and techniques throughout the region.

Cambodia, particularly during the Angkor period, was highly receptive to Indian mathematical concepts. The Khmer Empire adopted and adapted Indian mathematical ideas, which can be seen in their architecture, astronomy, and calendrical systems.

Indian mathematical concepts, such as trigonometry and spherical geometry, were used in Southeast Asia to develop accurate methods for calculating planetary positions. This knowledge was essential for creating calendars, predicting eclipses, and understanding the movement of celestial bodies.

The golden ratio, a specific proportion often found in nature and art, was widely used in Southeast Asian architecture. This ratio was incorporated into the design of temples, palaces, and other structures, creating aesthetically pleasing and harmonious proportions.

Indian mathematical concepts, particularly the use of symbols and notation, had a significant impact on the development of mathematics in Thailand. The Thai adopted and adapted Indian mathematical symbols, which simplified calculations and facilitated the exchange of mathematical ideas.

The golden ratio was used in the design of the Borobudur temple, a UNESCO World Heritage Site in Indonesia. The temple's dimensions, proportions, and overall layout reflect the application of this mathematical concept, creating a visually harmonious and aesthetically pleasing structure.

Indian mathematical concepts, such as astronomy and trigonometry, were used in Southeast Asia to develop new methods for calculating the length of the year. This knowledge was essential for creating accurate calendars, which were crucial for agricultural practices, religious observances, and other societal activities.

The concept of zero, introduced by Indian mathematicians, played a significant role in the development of navigation in Southeast Asia. The use of zero allowed sailors to accurately measure distances, calculate navigational routes, and determine their position at sea, leading to improved navigation techniques and safer seafaring.

Indian mathematical concepts, particularly methods for solving complex equations, had a significant impact on the development of mathematics in Vietnam. Vietnamese mathematicians adopted and adapted Indian techniques for solving algebraic and geometric problems, leading to advancements in mathematical knowledge and problem-solving skills.
