Solve 4(-1)+3-21div(-7)+3[-11(-2)-19]

$$4 ( - 1 ) + 3 - 21 \div ( - 7 ) + 3 [ - 11 ( - 2 ) - 19 ]$$

Evaluate

$$11$$

Solution Steps

Multiply 4 and -1 to get -4.

$$-4+3-\frac{21}{-7}+3\left(-11\left(-2\right)-19\right)$$

Add -4 and 3 to get -1.

$$-1-\frac{21}{-7}+3\left(-11\left(-2\right)-19\right)$$

Divide 21 by -7 to get -3.

$$-1-\left(-3\right)+3\left(-11\left(-2\right)-19\right)$$

The opposite of -3 is 3.

$$-1+3+3\left(-11\left(-2\right)-19\right)$$

Add -1 and 3 to get 2.

$$2+3\left(-11\left(-2\right)-19\right)$$

Multiply -11 and -2 to get 22.

$$2+3\left(22-19\right)$$

Subtract 19 from 22 to get 3.

$$2+3\times 3$$

Multiply 3 and 3 to get 9.

$$2+9$$

Add 2 and 9 to get 11.

$$11$$

Factor

$$11$$
