Solve 9-6{5+4[8+2(9-8*9)]}=

$$9 - 6 \{ 5 + 4 [ 8 + 2 ( 9 - 8 \times 9 ) ] \} =$$

Evaluate

$$2811$$

Solution Steps

Multiply 8 and 9 to get 72.

$$9-6\left(5+4\left(8+2\left(9-72\right)\right)\right)$$

Subtract 72 from 9 to get -63.

$$9-6\left(5+4\left(8+2\left(-63\right)\right)\right)$$

Multiply 2 and -63 to get -126.

$$9-6\left(5+4\left(8-126\right)\right)$$

Subtract 126 from 8 to get -118.

$$9-6\left(5+4\left(-118\right)\right)$$

Multiply 4 and -118 to get -472.

$$9-6\left(5-472\right)$$

Subtract 472 from 5 to get -467.

$$9-6\left(-467\right)$$

Multiply 6 and -467 to get -2802.

$$9-\left(-2802\right)$$

The opposite of -2802 is 2802.

$$9+2802$$

Add 9 and 2802 to get 2811.

$$2811$$

Factor

$$3\times 937$$
