Solve 13-4(5-2-6)+2-7(73-15+8)-(-12)

$$13 - 4 ( 5 - 2 - 6 ) + 2 - 7 ( 73 - 15 + 8 ) - ( - 12 )$$

Evaluate

$$-423$$

Solution Steps

Subtract 2 from 5 to get 3.

$$13-4\left(3-6\right)+2-7\left(73-15+8\right)-\left(-12\right)$$

Subtract 6 from 3 to get -3.

$$13-4\left(-3\right)+2-7\left(73-15+8\right)-\left(-12\right)$$

Multiply 4 and -3 to get -12.

$$13-\left(-12\right)+2-7\left(73-15+8\right)-\left(-12\right)$$

The opposite of -12 is 12.

$$13+12+2-7\left(73-15+8\right)-\left(-12\right)$$

Add 13 and 12 to get 25.

$$25+2-7\left(73-15+8\right)-\left(-12\right)$$

Add 25 and 2 to get 27.

$$27-7\left(73-15+8\right)-\left(-12\right)$$

Subtract 15 from 73 to get 58.

$$27-7\left(58+8\right)-\left(-12\right)$$

Add 58 and 8 to get 66.

$$27-7\times 66-\left(-12\right)$$

Multiply 7 and 66 to get 462.

$$27-462-\left(-12\right)$$

Subtract 462 from 27 to get -435.

$$-435-\left(-12\right)$$

The opposite of -12 is 12.

$$-435+12$$

Add -435 and 12 to get -423.

$$-423$$

Factor

$$-423$$
