hello..
You can easily do calculations with your mind just think is that you have to use your mind as quick as you can and you should feel relax during calculations and you can become calculation champion. Let me give you example how you can do calculations as fast as you want to.
Example
we've calculated that 6338 × 79 equals 500702
Sum the digits of 6338: (6 + 3 = 9, so count that as 0) + 3 + 8 = 11
Iterate as needed: 1 + 1 = 2
Sum the digits of 79: 7 + (9 counted as 0) = 7
Perform the original operation on the condensed operands, and sum digits: 2 × 7 = 14; 1 + 4 = 5
Sum the digits of 500702: 5 + 0 + 0 + (7 + 0 + 2 = 9, which counts as 0) = 5
5 = 5, so there's a good chance that we were right that 6338 × 79 equals 500702.
