Multiplier

Multiplier

In mathematics, to multiply means to add a number to itself a particular number of times.

Multiplication can be viewed as a process of repeated addition.

For example, \(4 \times 3\) is the same as \(3+3+3+3=12\)

multiplication is repeated addition

In this short lesson, we will learn about the multiplier and the multiplicand.

What Is Meant by Multiplier?

Meaning of Multiplier in Math

Look at the 3 groups of 7 cupcakes.

Multiplication using cupcakes

Instead of adding seven three times, we can write it as \( 7 \times 3 =21\)

This means there are 21 cupcakes in all.

Here, 7 is the multiplier and 3 is the multiplicand.

Multiplier and multiplicand are parts of multiplication statement.

How To Find a Product Using Multiplier? 

When we write a multiplication statement in a horizontal way, the leftmost number is the multiplier.

When we write a multiplication statement in a vertical way, the number on the top is the multiplier.

Look at the grid shown below.

Multiplication using grids

All the boxes contained in the grid correspond to the product of multiplier and multiplicand.

This is one of the easiest methods used for numbers with smaller quantities.

Experiment with the simulation below by using sliders to change multiplier and multiplicand and observe how the product changes.


 
important notes to remember
Important Notes
  1. If the multiplier is 1, then the values of product and multiplicand are equal.

  2. If the multiplier or the multiplicand is 0 in a multiplication statement, then the product is always equal to 0.

  3. Changing the order of multiplier and multiplicand in the multiplication statement does not make any difference to the product.

  4. The values of multiplier and multiplicand are always less than or equal to the product.

Solved Examples 

Example 1

 

 

Tom got 3 packs of trading cards and each pack had 5 cards in it.

multiplication example using trading cards

So, how many cards did Tom get in total?

Express this as a multiplication statement and state the multiplier and the multiplicand.

Solution

Number of cards in one pack of trading cards = 5

Number of cards in 3 packs of trading cards = \(5 \times 3=15\)

So, Tom got 15 cards in all.

The multiplier and the multiplicand are 5 and 3 respectively.
Example 2

 

 

A frog has to jump on every third tile without stepping on any number in between.

It starts jumping from the number 3

Jumping track game that uses multiples of 3

Can you list the tiles that he jumps on?

What is the multiplier here?

Solution

Let us color each 3rd tile as the frog jumps on the track.

Jumping track game that uses multiples of 3

We observe that the tiles that the frog jumps on are multiples of 3: 3, 6, 9, 12, 15, 18,...

So, the multiplier is 3

The following card contains an incomplete 5-column grid. 

Do appropriate calculations to find the missing numbers.

Finally, there are five selected numbers on each grid. Transfer them to the final column, and the last challenge is to find the sum all of these numbers.
