Subtraction

Subtraction is one of the four basic arithmetic operations. It is the opposite of addition. Subtraction represents the operation of removing a quantity, called the subtrahend, from another quantity, called the minuend. The result is called the difference. This operation is represented using the minus sign .
Subtraction is not commutative; this means that the order in which subtraction is performed matters, as different orders lead to different results.
