Solution Steps

The opposite of -15 is 15.

$$28+15-\left(-\left(2-6\right)-\left(-12-\left(-19+13\right)-4\right)+54\right)-\left(-47+25-8\right)$$

Add 28 and 15 to get 43.

$$43-\left(-\left(2-6\right)-\left(-12-\left(-19+13\right)-4\right)+54\right)-\left(-47+25-8\right)$$

Subtract 6 from 2 to get -4.

$$43-\left(-\left(-4\right)-\left(-12-\left(-19+13\right)-4\right)+54\right)-\left(-47+25-8\right)$$

The opposite of -4 is 4.

$$43-\left(4-\left(-12-\left(-19+13\right)-4\right)+54\right)-\left(-47+25-8\right)$$

Add -19 and 13 to get -6.

$$43-\left(4-\left(-12-\left(-6\right)-4\right)+54\right)-\left(-47+25-8\right)$$

The opposite of -6 is 6.

$$43-\left(4-\left(-12+6-4\right)+54\right)-\left(-47+25-8\right)$$

Add -12 and 6 to get -6.

$$43-\left(4-\left(-6-4\right)+54\right)-\left(-47+25-8\right)$$

Subtract 4 from -6 to get -10.

$$43-\left(4-\left(-10\right)+54\right)-\left(-47+25-8\right)$$

The opposite of -10 is 10.

$$43-\left(4+10+54\right)-\left(-47+25-8\right)$$

Add 4 and 10 to get 14.

$$43-\left(14+54\right)-\left(-47+25-8\right)$$

Add 14 and 54 to get 68.

$$43-68-\left(-47+25-8\right)$$

Subtract 68 from 43 to get -25.

$$-25-\left(-47+25-8\right)$$

Add -47 and 25 to get -22.

$$-25-\left(-22-8\right)$$

Subtract 8 from -22 to get -30.

$$-25-\left(-30\right)$$

The opposite of -30 is 30.

$$-25+30$$

Add -25 and 30 to get 5.

$$5$$

Factor
