$$2004 \times 1996+95 \times 91- { 2004 }^{ 2 } +8 \times 2004-16- { 93 }^{ 2 }$$

Evaluate

$$-20$$

Solution Steps

Multiply 2004 and 1996 to get 3999984. Multiply 95 and 91 to get 8645.

$$3999984+8645-2004^{2}+8\times 2004-16-93^{2}$$

Add 3999984 and 8645 to get 4008629.

$$4008629-2004^{2}+8\times 2004-16-93^{2}$$

Calculate 2004 to the power of 2 and get 4016016.

$$4008629-4016016+8\times 2004-16-93^{2}$$

Subtract 4016016 from 4008629 to get -7387.

$$-7387+8\times 2004-16-93^{2}$$

Multiply 8 and 2004 to get 16032.

$$-7387+16032-16-93^{2}$$

Add -7387 and 16032 to get 8645.

$$8645-16-93^{2}$$

Subtract 16 from 8645 to get 8629.

$$8629-93^{2}$$

Calculate 93 to the power of 2 and get 8649.

$$8629-8649$$

Subtract 8649 from 8629 to get -20.
