Answer

Estimate: 100,000; Exact: 70,180

Work Step by Step

There were 164,300 Confederate deaths from disease, and 94,120 Confederate deaths from battle. To estimate the difference, we round them to the nearest hundred-thousand and subtract to find the difference: 200,000 - 100,000 = 100,000. To find the exact difference, we subtract the actual numbers: 164,300 - 94,120 = 70,180
