Commutative property of multiplication

The commutative property of multiplication states that for any real numbers $a$ and $b$, $a\cdot b= b \cdot a$ If we let $a=7$ and $b= 11 \cdot 8$, the given statement is equivalent to: $a(b) = b(a)$. Thus, the given statement illustrates the commutative property of multiplication.
