$+$ and $\times$ on $\reals$
Terms
| Term | This example | Why |
|---|---|---|
| binary operation | ✓ | $+$ and $\times$ are binary operations on $\reals$ because they combine two real numbers into a new one: “$2 + 4$” produces $6$. |
| relation | ✗ | $+$ and $\times$ are not relations, because “$2 + 4$” does not have a true or false value. |
