Estimate: 200,000; Exact: 140,082

Work Step by Step

There were 250,152 Union deaths from disease, and 110,070 Union deaths from battle. To estimate, we round to the nearest hundred-thousand and subtract to find the difference: 300,000 - 100,000 = 200,000. To find the exact difference, we subtract the actual numbers: 250,152 - 110,070 = 140,082
