Solve 2--2^2+sqrt{1}-(-2+1)^2-5^1

$$2 - - 2 ^ { 2 } + \sqrt { 1 } - ( - 2 + 1 ) ^ { 2 } - 5 ^ { 1 }$$

Evaluate

$$1$$

Solution Steps

Calculate 2 to the power of 2 and get 4.

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

The opposite of -4 is 4.

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

Add 2 and 4 to get 6.

$$6+\sqrt{1}-\left(-2+1\right)^{2}-5^{1}$$

Calculate the square root of 1 and get 1.

$$6+1-\left(-2+1\right)^{2}-5^{1}$$

Add 6 and 1 to get 7.

$$7-\left(-2+1\right)^{2}-5^{1}$$

Add -2 and 1 to get -1.

$$7-\left(-1\right)^{2}-5^{1}$$

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

$$7-1-5^{1}$$

Subtract 1 from 7 to get 6.

$$6-5^{1}$$

Calculate 5 to the power of 1 and get 5.

$$6-5$$

Subtract 5 from 6 to get 1.

$$1$$

Factor

$$1$$
