👉 Trunk math, also known as the core or foundational mathematics, is the set of fundamental mathematical concepts and operations that form the basis for more advanced topics. It includes arithmetic, algebra, geometry, and basic number theory, providing the essential tools for problem-solving across various disciplines. Understanding these core principles is crucial as they underpin more complex mathematical ideas and real-world applications, from science and engineering to economics and data analysis. Mastery of trunk math enables students to build a strong foundation, facilitating deeper learning and more sophisticated mathematical thinking.
