The result is called the product, and "x" is the multiplier sign. From a philosophical point of view, multiplication is the result of a qualitative change caused by the quantitative change of addition. The multiplication of integers (including negative numbers), rational numbers (fractions), and real numbers is defined by the systematic generalization of this basic definition.

Multiplication Calculation Method:

A common method of using a pencil and paper multiplier requires a storage of a small number (usually any two numbers from 0 to 9) or a multiplication table for querying a product, but a farmer's multiplication algorithm is not.

Multiplying a number by more than a few decimal places is tedious and error-prone. Universal logarithms were invented.

to simplify this calculation. Slide rules allow numbers to be quickly multiplied by about three degrees of accuracy.

place. From the beginning of the twentieth century, mechanical calculators, such as the Marchant, automatically multiplied to 10 figures. Modern electronic computers.

And the calculator greatly reduces the need to multiply by hand.

Arithmetic operations are the "four operations", which are the collective name of the four operations of addition, subtraction, multiplication and division. It is usually performed on real or plural numbers. The two calendar numbers belonging to a certain set of numbers, after arithmetic operations, can determine the third number of this number set.

In computers, arithmetic operations also include operations such as finding absolute values, "negating", and "comparing" logical operations. (A small number of books say that the power and the square are also arithmetic operations).
