Multiplication
Definition

"Multiplication is nothing but repeated addition".

"It is denoted by "×"

Example: Count the number of apples on the trees.

Multiplication

This is a repeated addition. An easier and shorter method is to multiply 5 by 4,

i.e., 5×4 = 20.

Multiplication is Repeated Addition

Repeated addition means adding a series of the same number.

Multiplication is a short way for repeated addition.

Example:

4 ×7 means to add 4 times 7 or, 7 + 7 + 7 + 7 = 28.

Building The Tables

Groups of 6:

This means we are making many groups of 6 objects each.

So, we multiply by 6.

Example:

Tables Of 6

Count And Build The Table Of 6:

Multiplication

If we observe the tables of 5 and 6, we see a very interesting fact.

5 ×6 = 6 ×5 = 30.

We can easily observe the following facts from the tables we learnt so far:

  • 1×6=6×1=6
  • 2×6=6×2=12
  • 3×6=6×3=18
  • 4×6=6×4=24
  • 10×6=6×10=60

Table Of 7

Count And Build The Table Of 7.

Multiplication

Multiplication With The Help Of Tables

Table Of 4table Of 5

Multiplication

Multiplication On A Number Line

Multiply 5 By 3

Multiplication

Start from 0 and count by three with the method of skip counting.

5 jumps of 3 steps each.

5 jumps of 3= 5 ×3 = 15.

Multiplication Facts

Multiplying By 1:

1 student in the class.

Multiplication

Any number multiplied by 1 is the number itself.

Multiplication By 0:

There are no books in the book shelf.

Multiplication
Multiplication
Order Of Numbers

Multiplication

So, 6 ×5 = 30 = 5 ×6

Similarly, 4 ×3 = 12 = 3 ×4

7 ×8 = 56 = 8 ×7.

In this, two numbers multiplied in any order, have the same product.

Changing the order of the multiplicand and the multiplier does not change the product.

Multiplication Of A Two Digit Number By A 1_Digit Number

Let us consider an example to multiply 2_digit number by a 1_digit number.

Example: Multiply 32 by 2

Solution:

  • Multiply the ones.
  • 2 ones ×2 = 4 ones

  • Write 4 in the ones column.
  • Multiplication
  • Multiply the tens.
  • 3 tens ×2 = 6 tens

    Write 6 in the tens column.

Multiplication

Answer = 64.

Multiplication Of A 3_Digit Number By A 1_Digit Number

Example: Multiply 324 by 2.

Solution:

  • Multiply the ones.
  • 4 ones ×2 = 8 ones

  • Write 8 in the ones column.
  • Multiplication
  • Multiply the tens.
  • 2 tens ×2 = 4 tens

  • Write 4 in the tens column.
  • Multiplication
  • Multiply the hundreds.
  • 3 hundreds ×2 = 6 hundreds
  • Write 6 in the hundreds column.
Multiplication

Answer = 648.

Multiplication Of A 2_Digit Number By A 1_Digit Number By Regrouping And Carrying Over

Example: Multiply 42 by 8

Solution:

  • Multiply the ones.
  • 2 ones ×8 = 16 ones

  • Write 6 in the ones column and carry 1 ten to the tens column.
  • Multiplication
  • Multiply the tens.
  • 4 tens ×8 = 32 tens.

    32 tens + 1 ten = 33 tens

    33 tens = 3 hundreds + 3 tens

  • Write 3 tens in the tens column and 3 hundreds in the hundreds column.
Multiplication

Answer = 336.

Multiplication Of A 3_Digit Number By A 1_Digit Number By Regrouping And Carrying Over

Example: Multiply 186 by 3.

Solution:

  • Multiply the ones.
  • 6 ones ×3 = 18 ones.

    18 ones = 1 ten + 8 ones

  • Write 8 in the ones column and carry 1 ten to the tens column.
  • Multiplication
  • Multiply the tens
  • 8 tens ×3 = 24 tens

    24 tens + 1 ten = 25 tens

    25 tens = 2 hundreds + 5 tens

  • Write 5 tens in the tens column and carry 2 hundreds to the hundreds column.
  • Multiplication
  • Multiply the hundreds
  • 1 hundred ×3 = 3 hundreds

    3 hundreds + 2 hundreds = 5 hundreds.

  • Write 5 hundreds in the hundreds column.
Multiplication

Answer = 558.
