Solution Steps

The absolute value of a real number a is a when a\geq 0, or -a when a<0. The absolute value of -33 is 33.

$$-33-12+18+|45-40|=57$$

Subtract 12 from -33 to get -45.

$$-45+18+|45-40|=57$$

Add -45 and 18 to get -27.

$$-27+|45-40|=57$$

Subtract 40 from 45 to get 5.

$$-27+|5|=57$$

The absolute value of a real number a is a when a\geq 0, or -a when a<0. The absolute value of 5 is 5.

$$-27+5=57$$

Add -27 and 5 to get -22.

$$-22=57$$

Compare -22 and 57.

$$\text{false}$$
