This user page shows my strategies for mental calculations:

1 digit
Copy the number Eg.2×11=22

2 digits
First, write down the digits (use a pencil for the original tens digit/current hundreds digit) Next, add the 2 digits up Now, place it in the gap between the 2 digits After that, if it causes the tens digit to be too big, i will carry the extra digit

3 digits
Repeat above, except only write down the original first digit and last digit
