Solve 2^2*(-1/2)-16div(-2)^3

$$2 ^ { 2 } \times ( - \frac { 1 } { 2 } ) - 16 \div ( - 2 ) ^ { 3 }$$

Evaluate

$$0$$

Solution Steps

Calculate 2 to the power of 2 and get 4.

$$4\left(-\frac{1}{2}\right)-\frac{16}{\left(-2\right)^{3}}$$

Express 4\left(-\frac{1}{2}\right) as a single fraction.

$$\frac{4\left(-1\right)}{2}-\frac{16}{\left(-2\right)^{3}}$$

Multiply 4 and -1 to get -4.

$$\frac{-4}{2}-\frac{16}{\left(-2\right)^{3}}$$

Divide -4 by 2 to get -2.

$$-2-\frac{16}{\left(-2\right)^{3}}$$

Calculate -2 to the power of 3 and get -8.

$$-2-\frac{16}{-8}$$

Divide 16 by -8 to get -2.

$$-2-\left(-2\right)$$

The opposite of -2 is 2.

$$-2+2$$

Add -2 and 2 to get 0.

$$0$$

Factor

$$0$$
