Solve (-5):(-1)+[4+(3.2-1)*5-(6+7)]:2

$$( - 5 ) : ( - 1 ) + [ 4 + ( 3.2 - 1 ) \cdot 5 - ( 6 + 7 ) ] : 2$$

Evaluate

$$6$$

Solution Steps

Fraction \frac{-5}{-1} can be simplified to 5 by removing the negative sign from both the numerator and the denominator.

$$5+\frac{4+\left(3.2-1\right)\times 5-\left(6+7\right)}{2}$$

Subtract 1 from 3.2 to get 2.2.

$$5+\frac{4+2.2\times 5-\left(6+7\right)}{2}$$

Multiply 2.2 and 5 to get 11.

$$5+\frac{4+11-\left(6+7\right)}{2}$$

Add 4 and 11 to get 15.

$$5+\frac{15-\left(6+7\right)}{2}$$

Add 6 and 7 to get 13.

$$5+\frac{15-13}{2}$$

Subtract 13 from 15 to get 2.

$$5+\frac{2}{2}$$

Divide 2 by 2 to get 1.

$$5+1$$

Add 5 and 1 to get 6.

$$6$$

Factor

$$2\times 3$$
