Subtraction is really Addition
There is nothing magical about Subtraction, it is a form of Addition. It is the Addition of the opposite of the subtrahend to the minuend. The result is the same as the difference between the number.
Minuend: The first number in a subtraction. The number from which another number (the Subtrahend) is to be subtracted.
Subtrahend: The number that is to be subtracted. The second number in a subtraction.
Difference: The result of subtracting one number from another. How much one number differs from another.
Minuend - Subtrahend = Difference
