In this chapter, students explore the fundamental building blocks of mathematics through integers and number theory. Topics include operations with integers, understanding prime numbers, factors, multiples, greatest common factors (GCF), and least common multiples (LCM). Students also learn divisibility rules, the order of operations (BEDMAS), and strategies for efficient calculation. Through problem-solving, practice worksheets, and interactive exercises, students develop a strong foundation in numerical reasoning and analytical thinking, preparing them for more advanced mathematical concepts in future chapters..
