$\begin{aligned}&A=\{2,-2,3\} \quad B=\{1,-4\}\\&\mathbf{A}=\mathbf{B}=\{\mathbf{p}, \mathbf{q}\}\end{aligned}$

$\mathbf{A}=\{\mathbf{m}, \mathbf{n}\} ; \mathbf{B}=\varnothing$

$\begin{aligned}&A \times B=\{(2,1),(2,-4),(-2,1),(-2,-4),(3,1),(3,-4)\}\end{aligned}$

$A=\{2,-2,3\}$

$A \times A=\{(2,2),(2,-2),(2,3),(-2,2), (-2,-2),(-2,3),(3,2),(3,-2),(3,3)\}$

$\begin{aligned}&\mathrm{B} \times \mathrm{A}=>\mathrm{B}=\{1,-4\} ,\mathrm{A}=\{2,-2,3\}\\&\mathrm{B} \times \mathrm{A}=\{(1,2),(1,-2),(1,3),(-4, { 2), }(-4,-2),(-4,3)\}\end{aligned}$
