Also, as the result of multiplication does not depend on the order of the factors, the distinction between "multiplicand" and "multiplier" is useful only at a very elementary level and in some multiplication algorithms, such as the long multiplication. Therefore, in some sources, the term "multiplicand" is regarded as a synonym for "factor". [13]
In 1980, Everett L. Johnson proposed using the quarter square method in a digital multiplier. [11] To form the product of two 8-bit integers, for example, the digital device forms the sum and difference, looks both quantities up in a table of squares, takes the difference of the results, and divides by four by shifting two bits to the right.
The above-mentioned technique is inadequate when the multiplicand is the most negative number that can be represented (e.g. if the multiplicand has 4 bits then this value is −8). This is because then an overflow occurs when computing -m, the negation of the multiplicand, which is needed in order to set S.
This method starts by writing the multiplier above the multiplicand. The calculation begins by multiplying the multiplier only with the rightmost digit of the multiplicand and writing the result below, starting in the rightmost column. The same is done for each digit of the multiplicand and the result in each case is shifted one position to the ...
In mathematics, a product is the result of multiplication, or an expression that identifies objects (numbers or variables) to be multiplied, called factors.For example, 21 is the product of 3 and 7 (the result of multiplication), and (+) is the product of and (+) (indicating that the two factors should be multiplied together).
The main rules for the standard multiplication algorithm of whole numbers follow. In this multiplication procedure, "multiply the multiplicand by each digit of the multiplier and then add up all the appropriately shifted results". (West, [3] 2011) To utilize this method, it is necessary to know the basic multiplication table from zero to nine.
The multiplication sign is also used by historians for an event between two dates. When employed between two dates – for example 1225 and 1232 – the expression "1225×1232" means "no earlier than 1225 and no later than 1232". [8] A monadic × symbol is used by the APL programming language to denote the sign function.
Analog multiplier, a device that multiplies two analog signals; Frequency multiplier, a device that generates a signal at an integer multiple of its input frequency; Voltage multiplier, an electrical circuit that converts AC electrical power from a lower voltage to a higher DC voltage.
