Vähennysoperaattori

Vähennysoperaattori, or subtraction operator in English, is a fundamental arithmetic operation. It is used to find the difference between two numbers. The symbol for subtraction is a hyphen or minus sign (-). When one number is subtracted from another, the first number is called the minuend, and the second number is called the subtrahend. The result of the subtraction is known as the difference.

For example, in the expression 10 - 4 = 6, 10 is the minuend, 4 is the subtrahend, and 6 is the difference. Subtraction is the inverse operation of addition. If you add the subtrahend to the difference, you get the minuend. This property can be used to check the correctness of a subtraction.

Subtraction is used in various contexts, such as calculating remaining quantities, determining age differences, or finding the change from a purchase. In programming, the subtraction operator performs the same function on numerical data types. It is a core component of many algorithms and mathematical expressions. The order of operands in subtraction matters, as it is not a commutative operation, meaning a - b is not necessarily equal to b - a.
