Solve 12^2-14*1/2*(-1)+16*(-1^2)

$${ 12 }^{ 2 } -14 \times \frac{ 1 }{ 2 } \times (-1)+16 \times (- { 1 }^{ 2 } )$$

Evaluate

$$135$$

Solution Steps

Calculate 12 to the power of 2 and get 144.

$$144-14\times \frac{1}{2}\left(-1\right)+16\left(-1^{2}\right)$$

Multiply 14 and \frac{1}{2} to get \frac{14}{2}.

$$144-\frac{14}{2}\left(-1\right)+16\left(-1^{2}\right)$$

Divide 14 by 2 to get 7.

$$144-7\left(-1\right)+16\left(-1^{2}\right)$$

Multiply 7 and -1 to get -7.

$$144-\left(-7\right)+16\left(-1^{2}\right)$$

The opposite of -7 is 7.

$$144+7+16\left(-1^{2}\right)$$

Add 144 and 7 to get 151.

$$151+16\left(-1^{2}\right)$$

Calculate 1 to the power of 2 and get 1.

$$151+16\left(-1\right)$$

Multiply 16 and -1 to get -16.

$$151-16$$

Subtract 16 from 151 to get 135.

$$135$$

Factor

$$3^{3}\times 5$$
