Solve [9(3-7)-1]-[3-(2-4)]

$$[ 9 ( 3 - 7 ) - 1 ] - [ 3 - ( 2 - 4 ) ]$$

Evaluate

$$-42$$

Solution Steps

Subtract 7 from 3 to get -4.

$$9\left(-4\right)-1-\left(3-\left(2-4\right)\right)$$

Multiply 9 and -4 to get -36.

$$-36-1-\left(3-\left(2-4\right)\right)$$

Subtract 1 from -36 to get -37.

$$-37-\left(3-\left(2-4\right)\right)$$

Subtract 4 from 2 to get -2.

$$-37-\left(3-\left(-2\right)\right)$$

The opposite of -2 is 2.

$$-37-\left(3+2\right)$$

Add 3 and 2 to get 5.

$$-37-5$$

Subtract 5 from -37 to get -42.

$$-42$$

Factor
