Please study
the decimal number system
and
Addition ,
if you have not already done so.

They are prerequisites here.

Example 1 :

Suppose you have 5 packs of
chocolates and each pack has
2 chocolates in it. How many
chocolates do you have ?

You have 2 + 2 + 2 + 2 + 2
chocolates.

Using our knowledge of
Addition, we can find this
repeated addition as 10.

Since you have 5 packs of
2 chocolates, you have added 2,
five times and you got 10.

So, we can say 2 added 5 times
gives 10 or simply 5 times 2 is 10.

We write this as 5 x 2 = 10.

Example 2 :

You know, a cat has four legs.
Suppose there are 3 cats.
How many legs altogether ?

The answer is 4 + 4 + 4.
Using our knowledge of
Addition, we can find this
repeated addition as 4 + 4 + 4 = 12
or 3 times 4 is 12 or 3 x 4 = 12.

The above two examples are examples of
Multiplication as repeated addition.

Let us see one more example.

Example 3 : Multiplication as repeated addition

Do you know an octopus which lives
in sea ? How many legs does it have ?
It has 8 legs. How many legs
altogether 4 octopuses have ?

The legs they have is 8 + 8 + 8 + 8.
Using our knowledge of Addition,
we can find this repeated addition as
8 + 8 + 8 + 8 = 32
or 4 times 8 is 32 or 4 x 8 = 32.

In all these three examples,
we have seen repeated addition
of a number. Instead of writing the
number and the + symbol repeatedly,
we are counting how many times the
number is added and writing it
as that count x the number.

We say that the number is
multiplied by the count
and the process is called
mutiplication.

The symbol for multiplication is 'x'.

Thus, multiplication is nothing
but the repeated addition.
