Solve 34-12*(-3)+15-16div(-8-4-4)

$$34-12 \times (-3)+15-16 \div (-8-4-4)$$

Evaluate

$$86$$

Solution Steps

Multiply 12 and -3 to get -36.

$$34-\left(-36\right)+15-\frac{16}{-8-4-4}$$

The opposite of -36 is 36.

$$34+36+15-\frac{16}{-8-4-4}$$

Add 34 and 36 to get 70.

$$70+15-\frac{16}{-8-4-4}$$

Add 70 and 15 to get 85.

$$85-\frac{16}{-8-4-4}$$

Subtract 4 from -8 to get -12.

$$85-\frac{16}{-12-4}$$

Subtract 4 from -12 to get -16.

$$85-\frac{16}{-16}$$

Divide 16 by -16 to get -1.

$$85-\left(-1\right)$$

The opposite of -1 is 1.

$$85+1$$

Add 85 and 1 to get 86.

$$86$$

Factor

$$2\times 43$$
