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.
The best estimate for the sum of 4523 and 1234 can be found by rounding each number to the nearest hundred. Rounding 4523 to the nearest hundred gives 4500, and rounding 1234 to the nearest hundred gives 1200. Adding these rounded numbers gives an estimated sum of 5700. This estimate provides a quick approximation of the actual sum while simplifying the calculation.
Estimate by rounding to the nearest ten.​ Then, find the sum.221122plus+33554455​_​_The estimated sum is nothing.

Sum is the result of an addition problem, while difference is the result of a subtraction problem. Addend Subtractend + Addend - Subtractor Sum Difference
8/11 + 3/9 8/11 + 3/9
It is 10 + 7 = 17
No 100 is not a reasonable estimate
