What Is Subcision?

Subtraction is one of the four operations. The operation of subtracting one number from another is called subtraction; it is known that the sum of two addends and one of the addends. The sign for subtraction is "-", which is read as a minus sign.

Subtraction is a mathematical operation that represents the operation of removing an object from a collection. Its sign is a negative sign (). For example, in the picture on the right, there are 5-2 apples, 5 apples, and 2 are taken away, leaving only 3 apples. So 52 = 3. Subtraction means removing or reducing the amount of physics and abstraction with different objects (including negative numbers, fractions, irrational numbers, vectors, decimals, functions, and matrices).

When subtraction is used, there is a minus sign "-" between the two terms, and the result is represented by an equal sign. E.g,

In other cases, subtraction is "understanding", even if no symbols appear:

For a two-digit column, the smaller number is shown in red, which usually means that the smaller number in the column is to be subtracted, which is different from the following, below one line. This is common in accounting.

Formally, the number that is subtracted is called a subtraction, and the number that subtracts it is subtracted.

All these terms are derived from Latin. "Subtraction" is an English word derived from the Latin verb subtrahere, which is a compound of "from under" and "to pull", so it must be extracted from below and removed. The result of using the gerun diving suffix-nd is "subtracted" in "subtrahend". Also "reduce or reduce" from the minute, one gets "small" and "something decreases".

When two numbers are subtracted in units such as kilograms or pounds, they must have the same units. In most cases, the difference between the two is the same as the original number.

Vector addition and subtraction:

In linear algebra, a vector space is an algebraic structure that allows you to add any two vectors and scale vectors. A familiar vector space is the set of all ordered pairs of real numbers; the ordered pairs (a, b) are interpreted as vectors from the origin in the Euclidean plane to the point (a, b) in the plane. The difference between the two vectors is obtained by adding their respective coordinates:

This subtraction is the core of classical mechanics, where vectors are interpreted as forces.

Matrix subtraction:

Define matrix subtraction for two matrices of the same size. The difference between two m × n (pronounced "m by n") matrices A and B represented by A + B is a matrix calculated by subtracting elements, for example:
