**Multiplying Numbers**

Ok! now before you rush to kill us for explaining what you were
taught in 3

^{rd}grade in school let us tell you why exactly we are discussing about multiplying numbers! Certainly no question in any competitive exam will directly ask you to multiply two numbers but almost every other question will have you to multiplying numbers with numbers that lie between 11- 19.###
**Example of Multiplying Numbers from

A. 19882,
18176, 444824, 920268

B. 17992,
20176, 644734, 720268

**Conventional Method of Multiplying
Numbers from 11 to 19 with the Given Number**

So what is
your usual reaction on reading a question like this? You first multiply 1732
with 11 using the regular method where 1 is first multiplied with 2, then with
3, then 7 and so on… then you go to the next line, and start multiplying 1732
with 1 once again. Only this time you write the numbers in the tens place then
add them and get your answer. You follow this method for multiplying all the
numbers!

**Smart Method of Multiplying
Numbers from 11 to 19 with the Given Number**

Let’s
simplify this very complicated method of multiplying numbers for you and also
help you save some time in the process.

1732 x 11

**Step 1:**

Multiply the
number in the units place with the other number in the units place. In this
case multiply 1 with 2

**Step 2:**

For the second digit, multiply 1 with
3 and add the previous digit that is 2 in this case, so it will be 5

**Step 3:**

Move on with the remaining digits
multiplying with 1 and adding the previous digit in the same way. In case there
is a two digit number, carry it forward and add it.

Let’s try multiplying next two
numbers – 1598 x 12

**Step 1:**

Multiply the
number in the units place with the other number in the units place. In this
case multiply 2 with 8

**Step 2:**

Now in this
case 1 will be carried forward. We’ll multiply 2 with 9, and add 8 to it. We
get 26, to this we will add the carried forward 1 and so we get 27. Now 7 will
be written and 2 will be carried forward.

**Step 3:**

Similarly carry on with the entire
number and you’ll get the answer.

Isn’t this way more simple and quick!
This method can be used for multiplying numbers from 11 to 19 by this method.

Use this calculation trick while
multiplying numbers now-

Question 1: 34568 x 19 = ?

1) 656792 2) 566792 3) 700792 4) 665792

Question 2: 76432 x 13 = ?

1) 993116 2) 993616 3) 100616 4) 103116
