Solution Steps

Subtract 4 from 3 to get -1.

$$4\left(-5\left(2\left(-1\right)+7\left(42-43+2\right)+3\left(15-17\right)-3\left(12-14\right)+7\right)-3\left(21\left(39-39\right)-2\right)\right)$$

Multiply 2 and -1 to get -2.

$$4\left(-5\left(-2+7\left(42-43+2\right)+3\left(15-17\right)-3\left(12-14\right)+7\right)-3\left(21\left(39-39\right)-2\right)\right)$$

Subtract 43 from 42 to get -1.

$$4\left(-5\left(-2+7\left(-1+2\right)+3\left(15-17\right)-3\left(12-14\right)+7\right)-3\left(21\left(39-39\right)-2\right)\right)$$

Add -1 and 2 to get 1.

$$4\left(-5\left(-2+7+3\left(15-17\right)-3\left(12-14\right)+7\right)-3\left(21\left(39-39\right)-2\right)\right)$$

Add -2 and 7 to get 5.

$$4\left(-5\left(5+3\left(15-17\right)-3\left(12-14\right)+7\right)-3\left(21\left(39-39\right)-2\right)\right)$$

Subtract 17 from 15 to get -2.

$$4\left(-5\left(5+3\left(-2\right)-3\left(12-14\right)+7\right)-3\left(21\left(39-39\right)-2\right)\right)$$

Multiply 3 and -2 to get -6.

$$4\left(-5\left(5-6-3\left(12-14\right)+7\right)-3\left(21\left(39-39\right)-2\right)\right)$$

Subtract 6 from 5 to get -1.

$$4\left(-5\left(-1-3\left(12-14\right)+7\right)-3\left(21\left(39-39\right)-2\right)\right)$$

Subtract 14 from 12 to get -2.

$$4\left(-5\left(-1-3\left(-2\right)+7\right)-3\left(21\left(39-39\right)-2\right)\right)$$

Multiply 3 and -2 to get -6.

$$4\left(-5\left(-1-\left(-6\right)+7\right)-3\left(21\left(39-39\right)-2\right)\right)$$

The opposite of -6 is 6.

$$4\left(-5\left(-1+6+7\right)-3\left(21\left(39-39\right)-2\right)\right)$$

Add -1 and 6 to get 5.

$$4\left(-5\left(5+7\right)-3\left(21\left(39-39\right)-2\right)\right)$$

Add 5 and 7 to get 12.

$$4\left(-5\times 12-3\left(21\left(39-39\right)-2\right)\right)$$

Multiply -5 and 12 to get -60.

$$4\left(-60-3\left(21\left(39-39\right)-2\right)\right)$$

Subtract 39 from 39 to get 0.

$$4\left(-60-3\left(21\times 0-2\right)\right)$$

Multiply 21 and 0 to get 0.

$$4\left(-60-3\left(0-2\right)\right)$$

Subtract 2 from 0 to get -2.

$$4\left(-60-3\left(-2\right)\right)$$

Multiply 3 and -2 to get -6.

$$4\left(-60-\left(-6\right)\right)$$

The opposite of -6 is 6.

$$4\left(-60+6\right)$$

Add -60 and 6 to get -54.

$$4\left(-54\right)$$

Multiply 4 and -54 to get -216.
