Add the signed numbers as indicated: –22.42 + (–1.3) + 19.5 + 0.34 + (–13.89)

-22.42 + (-1.3) + 19.5 + 0.34 + (-13.89) = -17.67

To add the signed numbers step-by-step, follow these steps:

Step 1: Add -22.42 and -1.3
-22.42 + (-1.3) = -23.72

Step 2: Add the result from Step 1 to 19.5
-23.72 + 19.5 = -4.22

Step 3: Add the result from Step 2 to 0.34
-4.22 + 0.34 = -3.88

Step 4: Add the result from Step 3 to -13.89
-3.88 + (-13.89) = -17.77

Therefore, the sum of the signed numbers is -17.77.

To add signed numbers, follow these steps:

1. Start by adding the numbers with the same sign together. Positive numbers are added, and negative numbers are also added.

-22.42 + (–1.3) + 19.5 + 0.34 + (–13.89)

2. Combine the negative values: –22.42 + (–1.3) + (–13.89) = –37.61

3. Combine the positive values: 19.5 + 0.34 = 19.84

4. Add the two sums together to find the final answer: –37.61 + 19.84 = -17.77

Therefore, the sum of –22.42 + (–1.3) + 19.5 + 0.34 + (–13.89) is -17.77.
