SUMMARY

The discussion centers on the assertion by HallsofIvy that all mathematical statements can be expressed in the form "If A then B." Evagelos counters this by presenting axioms from propositional calculus, arguing that many mathematical statements are based on axioms and can be rephrased to fit the "if A then B" structure. The conversation highlights the nuances of mathematical logic, particularly the distinction between tautologies and conditional statements, and emphasizes that axioms themselves can be considered statements. The participants engage in a debate about the nature of mathematical statements and their foundational axioms.

PREREQUISITES
  • Understanding of propositional calculus and its axioms
  • Familiarity with formal logic concepts, particularly conditional statements
  • Knowledge of tautologies and their role in mathematical logic
  • Basic comprehension of mathematical statements and their implications
NEXT STEPS
  • Study the axioms of propositional calculus in detail
  • Explore the differences between tautologies and conditional statements in logic
  • Research the implications of axioms in mathematical proofs
  • Examine philosophical perspectives on the foundations of mathematics
USEFUL FOR

Mathematicians, philosophers of mathematics, students of logic, and anyone interested in the foundational principles of mathematical statements and their logical structures.

Yes, everyone seems to agree with HallsOfIvy already, except for one person :smile:

evagelos said:
Why when you substitute ...b---->a ,by B in ...a---->(b---->a) don't you hide the conditional ...a----->b?While is still there??

Hence...a----->(b----->a) it is not of the (if A then B ) form.
On the contray, it obviously is: A= a, B= (b---->a).

Your example is not very appropriate try to find another one
It was your example, not mine.
