Introduction

Addition is a fundamental arithmetic operation that is used in various aspects of mathematics, science, and everyday life. It involves combining two or more numbers to get a total or a sum. However, like any other mathematical operation, addition can be prone to errors, especially when dealing with large numbers or complex calculations. In this article, we will explore the concept of addition by one and identify which of the given examples is an error of addition by one.

What is Addition by One?

Addition by one, also known as a carry or a borrow, occurs when a digit in the addition process exceeds the maximum value of a single digit (i.e., 9). When this happens, the excess value is carried over to the next column, resulting in an increase of the sum by one. For example, in the addition of 17 and 25, the sum is 42. However, when we add 17 and 26, the sum is 43, which is an increase of one due to the carry-over of the excess value.

Analyzing the Examples

Let's analyze each of the given examples to determine which one is an error of addition by one.

A. $52,634 + 25,145 = 77,779$

In this example, the sum of $52,634 and $25,145 is indeed $77,779. There is no apparent error in the addition process, and the sum is correct.

B. $38,272 + 51,125 = 89,798$

In this example, the sum of $38,272 and $51,125 is indeed $89,398, not $89,798. This is an error of addition by one, as the correct sum is $89,398, not $89,798.

C. $13,246 + 84,631 = 97,877$

In this example, the sum of $13,246 and $84,631 is indeed $97,877. There is no apparent error in the addition process, and the sum is correct.

D. $46,371 + 32,618 = 78,989$

In this example, the sum of $46,371 and $32,618 is indeed $78,989. There is no apparent error in the addition process, and the sum is correct.

Conclusion

In conclusion, the error of addition by one is found in example B, where the sum of $38,272 and $51,125 is incorrectly stated as $89,798, when the correct sum is $89,398.

Why is Addition by One Important?

Addition by one is an essential concept in mathematics, as it helps to ensure the accuracy of calculations, especially when dealing with large numbers or complex arithmetic operations. It is also a critical concept in various fields, such as finance, science, and engineering, where accurate calculations are crucial.
