Solve (87-112)-(-98+113-37)-(99-142)=

$$( 87 - 112 ) - ( - 98 + 113 - 37 ) - ( 99 - 142 ) =$$

Evaluate

$$40$$

Solution Steps

Subtract 112 from 87 to get -25.

$$-25-\left(-98+113-37\right)-\left(99-142\right)$$

Add -98 and 113 to get 15.

$$-25-\left(15-37\right)-\left(99-142\right)$$

Subtract 37 from 15 to get -22.

$$-25-\left(-22\right)-\left(99-142\right)$$

The opposite of -22 is 22.

$$-25+22-\left(99-142\right)$$

Add -25 and 22 to get -3.

$$-3-\left(99-142\right)$$

Subtract 142 from 99 to get -43.

$$-3-\left(-43\right)$$

The opposite of -43 is 43.

$$-3+43$$

Add -3 and 43 to get 40.

$$40$$

Factor

$$2^{3}\times 5$$
