Divisibility of Integer Combinations states: For all integers a, b, and c, if a | b and a | c, then:

a) a | (b + c)
b) a | (b - c)
c) a | (b * c)
d) a | (b / c)

Final answer:

The student's question relates to divisibility rules for integers and how they apply to operations such as addition, subtraction, multiplication, but not universally to division.

Step-by-step explanation:

Understanding Divisibility of Integer Combinations

The question you've asked pertains to the fundamental divisibility rules within integers. Here's a concise explanation of each statement regarding integer divisibility:

  • Statement a) If an integer a divides both b and c, then a also divides their sum (b + c).
  • Statement b) Similarly, a divides the difference (b - c) of the two integers.
  • Statement c) When a divides both b and c, it naturally divides their product (b * c).
  • Statement d) The divisibility rule does not generally apply to division; that is, even if a divides b and c, it does not necessarily divide b / c, unless c is a multiple of a.

These rules help explain how the operations of addition, subtraction, and multiplication interact with divisibility but does not fully extend to division unless specific conditions are met.
