Solve 1/21/2+{left(1/2right)}^2-5^0

$$\frac{ 1 }{ 2 } \frac{ 1 }{ 2 } + { \left( \frac{ 1 }{ 2 } \right) }^{ 2 } - { 5 }^{ 0 }$$

Evaluate

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

Solution Steps

Multiply \frac{1}{2} and \frac{1}{2} to get \frac{1}{4}.

$$\frac{1}{4}+\left(\frac{1}{2}\right)^{2}-5^{0}$$

Calculate \frac{1}{2} to the power of 2 and get \frac{1}{4}.

$$\frac{1}{4}+\frac{1}{4}-5^{0}$$

Add \frac{1}{4} and \frac{1}{4} to get \frac{1}{2}.

$$\frac{1}{2}-5^{0}$$

Calculate 5 to the power of 0 and get 1.

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

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

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

Factor

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