Solve 40-20*(-6):4-5*(4+12:4)=

$$40 - 20 \cdot ( - 6 ) : 4 - 5 \cdot ( 4 + 12 : 4 ) =$$

Evaluate

$$35$$

Solution Steps

Multiply 20 and -6 to get -120.

$$40-\frac{-120}{4}-5\left(4+\frac{12}{4}\right)$$

Divide -120 by 4 to get -30.

$$40-\left(-30\right)-5\left(4+\frac{12}{4}\right)$$

The opposite of -30 is 30.

$$40+30-5\left(4+\frac{12}{4}\right)$$

Add 40 and 30 to get 70.

$$70-5\left(4+\frac{12}{4}\right)$$

Divide 12 by 4 to get 3.

$$70-5\left(4+3\right)$$

Add 4 and 3 to get 7.

$$70-5\times 7$$

Multiply 5 and 7 to get 35.

$$70-35$$

Subtract 35 from 70 to get 35.

$$35$$

Factor

$$5\times 7$$
