$$- 3 + ( 2 - 5 + 3 ) [ ( 4 + 5 - 7 ) - ( 4 - 7 + 2 ) ] - 7$$

Evaluate

$$-10$$

Solution Steps

Subtract 5 from 2 to get -3.

$$-3+\left(-3+3\right)\left(4+5-7-\left(4-7+2\right)\right)-7$$

Add -3 and 3 to get 0.

$$-3+0\left(4+5-7-\left(4-7+2\right)\right)-7$$

Add 4 and 5 to get 9.

$$-3+0\left(9-7-\left(4-7+2\right)\right)-7$$

Subtract 7 from 9 to get 2.

$$-3+0\left(2-\left(4-7+2\right)\right)-7$$

Subtract 7 from 4 to get -3.

$$-3+0\left(2-\left(-3+2\right)\right)-7$$

Add -3 and 2 to get -1.

$$-3+0\left(2-\left(-1\right)\right)-7$$

The opposite of -1 is 1.

$$-3+0\left(2+1\right)-7$$

Add 2 and 1 to get 3.

$$-3+0\times 3-7$$

Multiply 0 and 3 to get 0.

$$-3+0-7$$

Add -3 and 0 to get -3.

$$-3-7$$
