Evaluate

$$-11$$

Solution Steps

Subtract 3 from 7 to get 4.

$$3+6\times 4-20+4+3\left(-8\right)+3-7+4\left(2+5-8\right)+2\left(7-2\right)$$

Multiply 6 and 4 to get 24.

$$3+24-20+4+3\left(-8\right)+3-7+4\left(2+5-8\right)+2\left(7-2\right)$$

Add 3 and 24 to get 27.

$$27-20+4+3\left(-8\right)+3-7+4\left(2+5-8\right)+2\left(7-2\right)$$

Subtract 20 from 27 to get 7.

$$7+4+3\left(-8\right)+3-7+4\left(2+5-8\right)+2\left(7-2\right)$$

Add 7 and 4 to get 11.

$$11+3\left(-8\right)+3-7+4\left(2+5-8\right)+2\left(7-2\right)$$

Multiply 3 and -8 to get -24.

$$11-24+3-7+4\left(2+5-8\right)+2\left(7-2\right)$$

Subtract 24 from 11 to get -13.

$$-13+3-7+4\left(2+5-8\right)+2\left(7-2\right)$$

Add -13 and 3 to get -10.

$$-10-7+4\left(2+5-8\right)+2\left(7-2\right)$$

Subtract 7 from -10 to get -17.

$$-17+4\left(2+5-8\right)+2\left(7-2\right)$$

Add 2 and 5 to get 7.

$$-17+4\left(7-8\right)+2\left(7-2\right)$$

Subtract 8 from 7 to get -1.

$$-17+4\left(-1\right)+2\left(7-2\right)$$

Multiply 4 and -1 to get -4.

$$-17-4+2\left(7-2\right)$$

Subtract 4 from -17 to get -21.

$$-21+2\left(7-2\right)$$

Subtract 2 from 7 to get 5.

$$-21+2\times 5$$

Multiply 2 and 5 to get 10.

$$-21+10$$

Add -21 and 10 to get -11.

$$-11$$

Factor
