like you have to multiply two numbers say ( 26×27)

1. Substract unit digits

i.e. 26-6 = 20

27 - 7 = 20

2. Choose any number & add unit digit of other to other .

i.e. 27 + 6

or 26 + 7

I m taking, 27 + 6 = 33

3. Now multiply the added result to the result in first step .

i.e. 33 × 20 = 660

4. Now multiply unit digits

i.e. 6 × 7 = 42

5. Now add result of 3rd & 4th step

i.e. 660 + 42 = 702

Here is your answer
