Solve 9-[-(+7-15)+(+17-6-15)-6]-(15-27-10)

$$9 - [ - ( + 7 - 15 ) + ( + 17 - 6 - 15 ) - 6 ] - ( 15 - 27 - 10 )$$

Evaluate

$$33$$

Solution Steps

Subtract 15 from 7 to get -8.

$$9-\left(-\left(-8\right)+17-6-15-6\right)-\left(15-27-10\right)$$

The opposite of -8 is 8.

$$9-\left(8+17-6-15-6\right)-\left(15-27-10\right)$$

Add 8 and 17 to get 25.

$$9-\left(25-6-15-6\right)-\left(15-27-10\right)$$

Subtract 6 from 25 to get 19.

$$9-\left(19-15-6\right)-\left(15-27-10\right)$$

Subtract 15 from 19 to get 4.

$$9-\left(4-6\right)-\left(15-27-10\right)$$

Subtract 6 from 4 to get -2.

$$9-\left(-2\right)-\left(15-27-10\right)$$

The opposite of -2 is 2.

$$9+2-\left(15-27-10\right)$$

Add 9 and 2 to get 11.

$$11-\left(15-27-10\right)$$

Subtract 27 from 15 to get -12.

$$11-\left(-12-10\right)$$

Subtract 10 from -12 to get -22.

$$11-\left(-22\right)$$

The opposite of -22 is 22.

$$11+22$$

Add 11 and 22 to get 33.

$$33$$

Factor

$$3\times 11$$
