Work Step by Step

The addends have different signs, so to add them, perform the following steps: (1) Subtract the smaller absolute value from the bigger absolute value. $|-6.8|-|2.3| = 6.8-2.3 =4.5$ (2) The sum will have the same sign as the number with the bigger absolute value. $|-6.8|\gt |2.3|$ Thus, $-6.8+2.3=-4.5$
