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.

Oh, isn't that a lovely little math problem we have here? Let's see, if we round 4.204 to 4 and 2.779 to 3, then we can estimate the sum to be around 7. It's like adding up the happy little numbers in our painting, just giving us a general idea of what the total might be. Just a little estimation to help us along our mathematical journey.
