Solve 12(-7+[-4(2-3)-(-10-21))

$$12 ( - 7 + [ - 4 ( 2 - 3 ) - ( - 10 - 21 ) )$$

Evaluate

$$336$$

Solution Steps

Subtract 3 from 2 to get -1.

$$12\left(-7+-4\left(-1\right)-\left(-10-21\right)\right)$$

Multiply -4 and -1 to get 4.

$$12\left(-7+4-\left(-10-21\right)\right)$$

Subtract 21 from -10 to get -31.

$$12\left(-7+4-\left(-31\right)\right)$$

The opposite of -31 is 31.

$$12\left(-7+4+31\right)$$

Add 4 and 31 to get 35.

$$12\left(-7+35\right)$$

Add -7 and 35 to get 28.

$$12\times 28$$

Multiply 12 and 28 to get 336.

$$336$$

Factor

$$2^{4}\times 3\times 7$$
