Solve 8-9[3+6(1-3)+(4+9)]-4

$$8 - 9 [ 3 + 6 ( 1 - 3 ) + ( 4 + 9 ) ] - 4$$

Evaluate

$$-32$$

Solution Steps

Subtract 3 from 1 to get -2.

$$8-9\left(3+6\left(-2\right)+4+9\right)-4$$

Multiply 6 and -2 to get -12.

$$8-9\left(3-12+4+9\right)-4$$

Subtract 12 from 3 to get -9.

$$8-9\left(-9+4+9\right)-4$$

Add -9 and 4 to get -5.

$$8-9\left(-5+9\right)-4$$

Add -5 and 9 to get 4.

$$8-9\times 4-4$$

Multiply 9 and 4 to get 36.

$$8-36-4$$

Subtract 36 from 8 to get -28.

$$-28-4$$

Subtract 4 from -28 to get -32.

$$-32$$
