2 digit multiplication trick whose tens digit is same

Now, let us see the steps in detail

Step 1:To get the unit’s place digit to multiply the unit’s place digit of both the numbers.

Step 2:To get the ten’s place digit to multiply the ten’s place digit with its consecutive(next) number.

Step 3:Place the result obtained in step 2 to the left of the result obtained in step 1.

Let us now practice some examples

**Example 1: Multiply 26 x 24=? using the 2 digit Multiplication Trick**

We observe that ten’s place digit of both numbers=2

and by adding the unit’s place digit of both numbers(6+4=10)we get 10.

Hence, we can apply this trick

Step 1: Multiplying the unit’s place digits we get

Unit’s place digit=6 x 4=24

Step 2: Multiplying ten’s place digit by its consecutive number we get

Ten’s place digit=2 x 3=6

Step 3: Placing the result of step 2 to the left of the result obtained in step 1 we get

624

**Ans 26 x 24=624**

**Example 2: Multiply 43 x 47=? using the 2 digit Multiplication Trick**

We observe that ten’s place digit of both numbers=4

and by adding the unit’s place digit of both numbers(3+7=10) **we get 10 **

Step 1:Multiplying the unit’s place digits we get

Unit’s place digit=3 x 7=21

Step 2: Multiplying ten’s place digit by its consecutive number we get

Ten’s place digit=4 x 5=20

Step 3:Placing the result of step 2 to the left of the result obtained in step 1 we get

2021

**Ans 43 x 47=2021**

**Example 3: Multiply 38 x 32=? using the 2 Digit Multiplication Trick**

We observe that ten’s place digit of both numbers=3

and by adding the unit’s place digit of both numbers(8+2=10)we get 10

Step 1:Multiplying the unit’s place digits we get

Unit’s place digit=8 x 2=16

Step 2: Multiplying ten’s place digit by its consecutive number we get

Ten’s place digit=3 x 4=12

Step 3:Placing the result of step 2 to the left of the result obtained in step 1 we get

1216

**Ans 38 x 32=1216**

**Example 4: Evaluate this: 65 x 65=? using 2 digit Multiplication Trick**

We observe that ten’s place digit of both numbers=6

and by adding the unit’s place digit of both numbers(5+5=10)we get 10

Step 1:Multiplying the unit’s place digits we get

Unit’s place digit=1 x 9=09

Step 2: Multiplying ten’s place digit by its consecutive number we get

Ten’s place digit=7 x 8=56

Step 3:Placing the result of step 2 to the left of the result obtained in step 1 we get

5609

**Ans 71 x 79=5609**
