1. Let's state the problem: We need to add the three large numbers: $14,385,600,000 + 10,792,800,000 + 5,997,600,000$. 2. Add the first two numbers: $$14,385,600,000 + 10,792,800,000 = 25,178,400,000$$ 3. Now add the third number to the sum: $$25,178,400,000 + 5,997,600,000 = 31,176,000,000$$ 4. So, the final sum is: $$31,176,000,000$$ This is the total when you add all three numbers.
