When you have a negative number after the subtraction sign it turns in to addition.
For example +7 - (-7) = 14
and (-7) - 7 = (-14)
Subtraction, like addition, results in a sum.
No. The sum is the answer to an addition problem. The difference is the answer to a subtraction problem.
In mathematical operations, addition, subtraction, and multiplication are governed by the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)). When addition, subtraction, and multiplication are used in a problem, multiplication is performed first, followed by addition and subtraction, which are executed from left to right. Thus, in a sequence where these operations appear together, multiplication takes priority over addition and subtraction.
multiplication - product division - quotient addition - summation subtraction - difference
You can use addition to check your answer to a subtraction problem because subtraction is the inverse operation of addition. If you subtract a number from another and then add that same number back to your result, you should arrive at the original number. This relationship confirms the accuracy of your subtraction result, ensuring that the calculations are correct. If the sum does not match the original number, then there was likely an error in the subtraction process.
addition Sum is the result of an addition problem. Difference is the result of a subtraction problem.

Answer for an addition problem= sum. Answer for a subtraction problem= difference. Answer for a multiplication problem= product. Answer for a division problem= quotient.

A multiplication problem's answer is called a product. For a addition or subtraction problem it is called a sum.
A subtraction problem can always be written as an addition problem by using the concept of "adding the opposite." For example, the subtraction equation (a - b) can be transformed into the addition equation (a + (-b)). This representation helps to maintain the same numerical relationship while expressing it in a different mathematical form.
in a multiplication problem, you don't have to. in addition & subtraction, you do
P.E.M.D.A.S is how i remember it Parentheses Exponent Multiplication Division Addition Subtraction also, whichever comes first in the problem goes first, but this only works with multiplication and division and also addition and subtraction but only multiplication with division and addition with subtraction
who discovered addition and subtraction.
