subtractioon

Subtraction is a fundamental arithmetic operation, one of the four basic operations alongside addition, multiplication, and division. It is commonly understood as the process of taking away a quantity from another quantity. The symbol used to denote subtraction is a hyphen (-).

When we subtract one number from another, the result is called the difference. The number from which another number is subtracted is called the minuend, and the number being subtracted is called the subtrahend. For example, in the equation 7 - 3 = 4, 7 is the minuend, 3 is the subtrahend, and 4 is the difference.

Subtraction is the inverse operation of addition. This means that if you add the subtrahend back to the difference, you will get the original minuend. Continuing the example, 4 + 3 = 7. This relationship can be used to check the accuracy of a subtraction problem.

The concept of subtraction extends beyond simple numbers. It can be applied to various mathematical objects, including polynomials, vectors, and matrices, though the specific rules for subtraction may vary. In set theory, subtraction can be represented as set difference, where elements are removed from one set that are also present in another.

Subtraction is a crucial skill in mathematics and is used extensively in everyday life, from managing personal finances to solving complex scientific problems. Its meaning of "taking away" or "finding the difference" is intuitive and widely applicable.
