Solve 2*[(4-3)-(5-9-2)+(7+4)]

$$2 \cdot [ ( 4 - 3 ) - ( 5 - 9 - 2 ) + ( 7 + 4 ) ]$$

Evaluate

$$36$$

Solution Steps

Subtract 3 from 4 to get 1.

$$2\left(1-\left(5-9-2\right)+7+4\right)$$

Subtract 9 from 5 to get -4.

$$2\left(1-\left(-4-2\right)+7+4\right)$$

Subtract 2 from -4 to get -6.

$$2\left(1-\left(-6\right)+7+4\right)$$

The opposite of -6 is 6.

$$2\left(1+6+7+4\right)$$

Add 1 and 6 to get 7.

$$2\left(7+7+4\right)$$

Add 7 and 7 to get 14.

$$2\left(14+4\right)$$

Add 14 and 4 to get 18.

$$2\times 18$$

Multiply 2 and 18 to get 36.

$$36$$

Factor

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