$$10 \times { 1 }^{ 2 } +3 \times 1 \times { 1 }^{ 2 } - { 1 }^{ 2 } - { 1 }^{ 3 }$$
$11$
$$10\times 1^{2}+3\times 1^{3}-1^{2}-1^{3}$$
$$10\times 1+3\times 1^{3}-1^{2}-1^{3}$$
$$10+3\times 1^{3}-1^{2}-1^{3}$$
$$10+3\times 1-1^{2}-1^{3}$$
$$10+3-1^{2}-1^{3}$$
$$13-1^{2}-1^{3}$$
$$13-1-1^{3}$$
$$12-1^{3}$$
$$12-1$$
$$11$$
