👉 In mathematics, a subtracter is a mathematical function that takes two operands and returns their difference. It can be defined as:
f(x) = x - y
where x and y are the two operands.
For example, if we have the expression f(x) = 3x - 5, then the value of the function at x = 2 is f(2) = 3
2 - 5 = 4.
