Answer 1

Hello

The question here relates to property of real numbers and it's called commutative property of multiplication

commutative property of multiplication states that

x.y = y.x

$\begin{gathered} 5\cdot n\cdot2=0 \\ 10\cdot n=0 \\ n=\frac{0}{10} \\ n=0 \end{gathered}$

note: zero property of multiplication was also used in this case since any number multiplied by zero is equal to zero
