integer properties
summary
this content delves into the fundamental concepts of integer properties, focusing on factors, divisors, and divisibility, which are crucial for understanding and solving act exam questions.
- integer properties encompass the study of non-fraction numbers, including positive whole numbers, zero, and negative whole numbers.
- key terms essential for the act exam include factor, divisor, and divisible, with detailed explanations and examples provided for each.
- the process of division is explored, highlighting two outcomes: integer quotients with remainders and non-integer quotients expressed as fractions or decimals.
- a systematic approach to finding all positive factors of a number is outlined, emphasizing the listing of factor pairs.
- for larger numbers, an efficient technique for determining the number of factors is promised, with a note on the technical possibility of negative factors and divisors.
