Subtraction related more information:

Subtraction is an arithmetic operation that represents the removal of objects from a set.[1] Subtraction is represented by a minus sign, −. For example, the adjacent image shows 5-2 peaches - that is, 5 peaches with 2 removed, for a total of 3 peaches. Therefore the difference of 5 and 2 is 3; that is, 5 − 2 = 3. Although in arithmetic it is primarily associated with natural numbers, subtraction can also refer to the removal or reduction of physical and abstract quantities using a variety of objects, including negative numbers, fractions, irrational numbers, vectors, decimals, functions, and matrices. Subtraction follows many important patterns. It is anticommutative, meaning that changing the order changes the sign of the answer. It is also non-associative, meaning that if more than two numbers are subtracted, the order of subtraction matters. Since 0 is an additive identity, subtracting it does not change the number. Subtraction also follows predictable rules for related operations such as addition and multiplication. All of these rules can be proved starting from subtracting integers and generalizing through the real numbers and beyond. General binary operations that follow these patterns are studied in abstract algebra.
