SUMMARY

The discussion focuses on translating the statement "The square of every odd integer is one more than an integral multiple of 4" into symbolic logic. The proposed symbolic representation is $$\forall n \in \mathbb Z: n\text{ odd} \to n^2 \bmod 4 = 1$$. Additionally, a more detailed expression is suggested: $$\forall m\exists n\,(2m+1)(2m+1)=4n+1$$. The importance of specifying the signature and interpretation of symbols in logical statements is emphasized for clarity.

PREREQUISITES
  • Understanding of symbolic logic notation
  • Familiarity with mathematical concepts of odd integers and modular arithmetic
  • Knowledge of quantifiers in logic, specifically universal and existential quantifiers
  • Basic understanding of logical predicates and functions
NEXT STEPS
  • Study the principles of translating natural language statements into symbolic logic
  • Learn about modular arithmetic and its applications in number theory
  • Explore the use of quantifiers in formal logic
  • Research the significance of signatures in logical expressions and their interpretations
USEFUL FOR

Students of mathematics, logic enthusiasts, and educators looking to deepen their understanding of symbolic logic and its applications in formal reasoning.

Dear Everyone,

I need to translate this following statement into a symbolic logical form of the statement:

The square of every odd integer is one more than an integral multiple of 4.

Thanks,

Something like:
$$\forall n \in \mathbb Z: n\text{ odd} \to n^2 \bmod 4 = 1$$
? (Wondering)

You can denote the whole statement by a single letter, say, $P$. This is to show that in order to make the problem meaningful, the problem author must specify the signature, or vocabulary: constants, functional symbols and predicate symbols that can be used in the formula. Ideally the author should also specify the interpretation of that signature because this statement is written differently over natural numbers and over reals.

But, guessing the author's intent, the answer is probably
\[
\forall m\exists n\,(2m+1)(2m+1)=4n+1.
\]
