What is Meant by Estimate Sum?

In Maths, when two whole numbers are added, the outcome is called addition or summation. During the addition of numbers, there are two possible ways that can be used to solve. One is for getting the actual addition of numbers and the other is the estimated sum.

If we find the exact addition then it is called the actual addition. The estimated sum means the addition of given numbers by rounding off to the nearest ten, hundred, and thousand places. The result of given whole numbers using the Estimation of Sum method won't give the exact summation, but it gives close value to the exact sum.

For example, Sum of 37 and 58. The actual addition is 37+58 = 95. The estimated sum is 40+60 = 100.

Steps to Estimate the Sum of Two Numbers

Estimation of Sum is a simple and easy concept to perform. It doesn't give the exact summation result after simplifying the given numbers using the estimated sum method. The steps that are followed to find the estimated sum are as follows:

  • First, take the two given whole numbers.
  • Now, consider the first number and round off the number to the nearest 10 place value.
  • Again repeat the same step for the second number ie., round off to the nearest 10 place value.
  • Next, Add those two rounded values and get the estimated sum for the given numbers.

By following these simple steps you will make your calculations easily and quickly. For more knowledge, we have compiled a solved example for finding the estimated sum for two numbers ie., 567 and 349 along with the show work. So, let's have a glance at the explanation.


What is the estimated sum of 567 and 349?


Given, two numbers are 567 and 349

First, round up the first number to the nearest 10's place value ie., 567 to 570.


Now, round up the second number to the nearest 10's place value ie., 349 to 350.


Add 570 and 350

= 920


∴ The Estimated Sum of 567+349 is 920.
