Symmetric Property of Equality

Pronunciation: /sɪˈmɛ.trɪk ˈpɹɑp.ər.ti ʌv ɪˈkwɒl.ɪ.ti/ Explain

The symmetric property of equality for real numbers states that if a = b, then b = a.


Is less than (<) symmetric for real numbers? If it is symmetric, then for all real numbers, if a < b then b < a. Can you find a pair of numbers for which this is not true? Write a proof for your conclusion.
