Multiplication: First Principles


    what you'll learn...

overview

This page introduces multiplication of whole numbers as -- one number, multiplicand, is repeated the number of times given by the second number, multiplier. The combined result of the repetition is counted or measured as the product of the multiplication. multiplication of two numbers Count of 3 cars is repeated 4 number of times. The resulting count is 12. multiplication of two numbers Measure of 3 is repeated 4 times. The resulting measure is 12.

The same is abstracted for multiplication in number-line. multiplication of two numbers The definition of multiplication in first principles form the basis to understanding the simplified procedure for multiplication of large numbers.

repeated addition

multiplication two numbers

3 cars were given to 4 show rooms each.

The total number of cars given are 12.

The problem is understood to be that of repeated addition.

3 cars were given to the first show room, then to the second, then to the third, and then to the fourth. So 3 was repeatedly added 4 times to get the total.

multiplication two numbers

Considering 3 cars given to 4 show rooms each. All the cars are shown in the figure. Counting the number of cars, the result is 12.

multiplication two numbers

There are 4 pencils, each of 3 centimeter long.

The combined length of the pencils is 12 centimeter.

The problem is understood to be that of repeated addition.

Length of one pencil is 3 centimeters. To get the combined length of 4 such pencils, the length is repeatedly added 4 times.

multiplication two numbers

Considering 4 pencils, each of 3 centimeter long. The four pencils are placed side-by-side and the length measurement is taken from 0. The measure at the end is 12. The combined length is 12 centimeters.

The count or measure of a quantity can be repeatedly added or multiplied.

The multiplication results in count or measure of the combined quantity.

multiplication two numbers

Multiplication 3×4 in the number-line is given in the figure.

The value 3 is repeated 4 times to land in 12. The result of the multiplication is 12.

The word "multiplication" means: increase in quantity many times over.

multiplicant, multiplier, product

Multiplication - First Principles : Two numbers are considered, each of which represents a count or measurement. One of the amount is repeated the number of times given by the second amount to form the result representing the collective amount from such repetition.

eg: 12×3=36

12 is the multiplicand

3 is the multiplier

36 is the product

The word "multiplicand" means: the number or quantity that is repeatedly added in a multiplication.

The word "multiplier" means: the number of times a quantity is repeatedly added.

The word "product" means: the result of multiplication.
