Solve [-1+(2^2-5*6)]div(-5+2)+1=

$$[ - 1 + ( 2 ^ { 2 } - 5 \cdot 6 ) ] \div ( - 5 + 2 ) + 1 =$$

Evaluate

$$10$$

Solution Steps

Calculate 2 to the power of 2 and get 4.

$$\frac{-1+4-5\times 6}{-5+2}+1$$

Multiply 5 and 6 to get 30.

$$\frac{-1+4-30}{-5+2}+1$$

Subtract 30 from 4 to get -26.

$$\frac{-1-26}{-5+2}+1$$

Subtract 26 from -1 to get -27.

$$\frac{-27}{-5+2}+1$$

Add -5 and 2 to get -3.

$$\frac{-27}{-3}+1$$

Divide -27 by -3 to get 9.

$$9+1$$

Add 9 and 1 to get 10.

$$10$$

Factor

$$2\times 5$$
