We can say that,

$Checking Subtraction$

How can you use addition to check the answer of subtraction? How can you use subtraction to check the answer of addition?

Addition (+) and subtraction (-) are opposite operations in math, so you can use one to check the answer of the other one.

For example

1. 2 + 3 = 5

5 - 3 = 2

The first way says, if we start with 2 and add 3, we get 5. The second way says, if we start with 5 and take away 3, we get 2. We are just playing with the same numbers forward and backward.

$Check for Addition Answer$

Thus, 6476 - 2365 = 4111 is true as 2365 + 4111 = 6476. Similarly, the sum of two numbers is true if the difference between the sum and the first number is equal to the second number, i.e., 2365 + 4111 = 6476 is true as 6476 - 4111 = 2365 or 6476 - 2365 is equal to 4111.
