Question

$$\frac{1^{2}-2^{-1}}{-1}$$

Evaluate

$-\frac{1}{2}=-0.5$

Solution Steps

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

$$\frac{1-2^{-1}}{-1}$$

Calculate $2$ to the power of $-1$ and get $\frac{1}{2}$.

$$\frac{1-\frac{1}{2}}{-1}$$

Subtract $\frac{1}{2}$ from $1$ to get $\frac{1}{2}$.

$$\frac{\frac{1}{2}}{-1}$$

Express $\frac{\frac{1}{2}}{-1}$ as a single fraction.

$$\frac{1}{2\left(-1\right)}$$

Multiply $2$ and $-1$ to get $-2$.

$$\frac{1}{-2}$$

Fraction $\frac{1}{-2}$ can be rewritten as $-\frac{1}{2}$ by extracting the negative sign.

$$-\frac{1}{2}$$

Factor

$-\frac{1}{2} = -0.5$
