Solve -(-1)^2+10*(-1)*2-10*2^2

$$- ( - 1 ) ^ { 2 } + 10 \times ( - 1 ) \times 2 - 10 \times 2 ^ { 2 }$$

Evaluate

$$-61$$

Solution Steps

Calculate -1 to the power of 2 and get 1.

$$-1+10\left(-1\right)\times 2-10\times 2^{2}$$

Multiply 10 and -1 to get -10.

$$-1-10\times 2-10\times 2^{2}$$

Multiply -10 and 2 to get -20.

$$-1-20-10\times 2^{2}$$

Subtract 20 from -1 to get -21.

$$-21-10\times 2^{2}$$

Calculate 2 to the power of 2 and get 4.

$$-21-10\times 4$$

Multiply 10 and 4 to get 40.

$$-21-40$$

Subtract 40 from -21 to get -61.

$$-61$$

Factor
