rounding
8 and 6 have a difference of 2 and a sum of 14.
To estimate the sum is to guess what the answer is for an addition problem. For example, if it was 8 + 9 you would see what number 8 is close to (like ten) and do the same with number nine and your estimate would be 20.

46.78-18.55 and estimate each sum or difference = 28.23
The sum is 2.05 and you don;t need to estimate such a simple sum!

In arithmetic, estimate usually means rounding the numbers so they're easier to manipulate. Example: Estimate the sum of 432 and 267. You can round them to 430 and 270 and estimate the sum as 700. You could also round them to 400 and 300 and estimate the same total. To estimate a difference, just subtract them. 430 minus 270 is 160. The actual sum is 699 and the actual difference is 165, so your estimates came pretty close.
