Easy Multiplication Shortcut 2

Multiplying 2-digit numbers where the Ten’s digit add up to 10 and Unit digits are same.
Find the multiplication of two numbers AB & CB (where  A + C = 10)
then we can follow the following steps
1.  First find the multiplication of last two digit of both the numbers i.e. Find B x B. It will give us last 2 digits of the answer.
2. Multiply the Ten’s digits and Add the common digit to the multiplication ie. find  AxC + B. It will give us the initial digits of the multiplication.

 Ex: 44 × 64?
1.  Here ten’s digit are 4 and 6 and their sum is 10 and unit digits of both numbers are same. Multiplying the        unit digits, we get 4 × 4 = 16. Put it at right hand side.
2.  Again multiplying the ten’s digits of numbers and adding common digit,
     we get (4 × 6) + 4 = 24 + 4 = 28. Put it at the left hand side. So, we get required answer as 2816.
