First let me introduce you about what are “teen numbers “.

**Teen Numbers** are numbers from 11 to 19 .

Now let’s look into multiplying the two teen numbers.

**Steps involved are as follows**.

1 ) To one of the numbers , add the units digit of the other number.

2 ) Find the product of units digit of two numbers.

3 ) Any tens digit should be added to the sum found in the first step.

4 ) Affix the two results of the above steps : step 1| step 2

Consider for example :

12 ×17

Step 1 : 12 +7 = 19 or 17+2 = 19

Step 2: 7×2 = 14

Step 3: Now add 1 from step 2 to 9 (step 1)

Step 4 : we get 1/ (9+1)/3

= 204

Therefore, 12 ×17 =204

One more example

13×19 = ( 13+9) / (3×9)

= 22/27

=247

* Try it yourself* :

a) 12 × 16 =?

b) 13 ×17 =?

c) 18 ×13 =?
