Definition
yes
No, because the reverse statement may not result in a true statement.(A) If x is an integer then x*x is rational.(B) if x*x is rational then x is an integer.(B) is utter nonsense. x can be any rational number of even a square root of a rational number, for example, sqrt(2/3), and x*x will be rational.
Deductive reasoning In mathematics, a proof is a deductive argument for a mathematical statement. Deductive reasoning, unlike inductive reasoning, is a valid form of proof. It is, in fact, the way in which geometric proofs are written.
Conditional
As written it is in standard notation In mathematical notation it would be; 1.3 × 1014
yes
a statement that clearly describes the problem to be solved
The early Germanic kingdoms were characterized by decentralized political structures with a strong emphasis on kinship ties and warrior-based societies. They often engaged in raiding, warfare, and inter-tribal conflicts, which played a central role in their social and political organization. The kingdoms were often fluid and subject to frequent changes in leadership and territorial boundaries.

How can the following definition be written correctly as a biconditional statement? An odd integer is an integer that is not divisible by two. (A+ answer) An integer is odd if and only if it is not divisible by two
