We will learn to check for subtraction and addition answers after solving.
Difference of two numbers is correct when the sum of the subtrahend number and the difference is equal to the minuend.
We can say that,
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.
2.
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.
