True

#### Work Step by Step

This is an example of the commutative property of multiplication, where the order of the numbers changes, but the product stays the same.
For example, if $r=2, s=3, t=4$, then the equation is $(2\times3)\times4=4\times(3\times2)$ is $6\times4=4\times6$. This reduces to $24=24$.
