If you calculated x - y = z
then calculate z + y.
If the answer is x your calculation is fine. If not, one of the sums went wrong.
An operation usually used in solving equations which is the exact opposite of the original problem in order to isolate the variable. Addition and subtraction are inverse operations. Squaring and square roots are opposites. etc
You bring it straight down.
Order of Operations is like when you have a problem i always use PEMDAS it means parenthesis, expoents, mulitipication, divide, addition, Subtraction follow it.
Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction
Addition can be used to solve a subtraction problem by using the concept of inverse operations. By adding the opposite of a number to another number, the result will be the same as subtracting the first number from the second number. This can be helpful in mental math or when trying to simplify complex subtraction problems.

If you have calculated A + B = C then you can calculate C - A. If the answer is B then the first sum is correct.
You bring it straight down.
in a multiplication problem, you don't have to. in addition & subtraction, you do
people use inverse operations when there is a number like -3 then you change it to a regular problem like 3. you use it when something is opposite to the regular problem.
Add the result of the subtraction to the number you were subtracting and you should get the number from which you subtracted. example 246.8 - 35.15 = 211.65 To check add 211.65 + 35.15 and see if you get 246.8

The answer in a subtraction problem is difference.

No, the answer in a subtraction problem is the difference.
It is the order of operations involving a mathematical problem which includes brackets, indices, multiplication, division, addition and subtraction.
