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

$$2 \times ((4-3)-(5-9-2)+(7-4))$$

Evaluate

$$20$$

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.

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

Subtract 4 from 14 to get 10.

$$2\times 10$$

Multiply 2 and 10 to get 20.

$$20$$

Factor

$$2^{2}\times 5$$
