The property of real numbers illustrated by the equation $\pi \cdot 3 = 3 \cdot \pi$ is the commutative property of multiplication. This property states that for any real numbers $a$ and $b$, $a \cdot b = b \cdot a$. In this case, $\pi \cdot 3 = 3 \cdot \pi$ shows that the order of the factors does not affect the product.
The property illustrated by the equation π * 3 = 3 * π is the commutative property of multiplication. This property states that the order in which numbers are multiplied does not affect the result. In this case, π (pi) and 3 are being multiplied, and regardless of whether π is multiplied by 3 or 3 is multiplied by π, the result will be the same.
