Solve (-1)^2+(1/2)^-1-5div(2006+pi)^0

$$( - 1 ) ^ { 2 } + ( \frac { 1 } { 2 } ) ^ { - 1 } - 5 \div ( 2006 + \pi ) ^ { 0 }$$

Evaluate

$$-2$$

Solution Steps

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

$$1+\left(\frac{1}{2}\right)^{-1}-\frac{5}{\left(2006+\pi \right)^{0}}$$

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

$$1+2-\frac{5}{\left(2006+\pi \right)^{0}}$$

Add 1 and 2 to get 3.

$$3-\frac{5}{\left(2006+\pi \right)^{0}}$$

Calculate 2006+\pi to the power of 0 and get 1.

$$3-\frac{5}{1}$$

Anything divided by one gives itself.

$$3-5$$

Subtract 5 from 3 to get -2.

$$-2$$

Factor

$$-2$$
