https://proofwiki.org/wiki/Real_Numbers_form_Integral_Domain | # Real Numbers form Integral Domain
## Theorem
The set of real numbers $\R$ forms an integral domain under addition and multiplication: $\struct {\R, +, \times}$.
## Proof
Recall that Real Numbers form Field.
The result then follows directly from Field is Integral Domain.
