I have one more trick for you all take a look at it, with this trick will be able to do long addition with in 2secs. Yes mark my word!!!
Ask your friend to write any five figure number. Then you write your five figure number under it. You choose yours so that each one with the calculation above will make nine. For example, his number 45 623 your number 54 376 Tell your friend to put a third five figure number and then you write your number 45623 + 54376 + 27043 + 72956 Finally, ask him to write the Fifth figure number and then Draw a line under it and quickly write the sum. 45623 + 54376 + 27043 + 72956 + 48765 ------------------------- 248763 ------------------------- To get the answer quickly all you have to do is subtract 2 from the Last fifth number(5-3) and put 2 in front of the number. Here is it, the number you'll get is your the answer. Now why i have subtracted & added '2' the reason is simple if you sum up the 1st two number it will bring you total as 99999 and similarly for 3rd & 4th number so total we have 2x(99999) and that's the reason we are adding & subtracting by 2. So you & your friend just keep on writing the numbers in the list and at the end we just have to add & subtracts the times we are having 99999 in our list. Feel free to ask me anything if you find any thing to difficult. Try out this trick with your friend & Be A Math Genius. Become an amazing Math Magician::The secrets of Mental Math: |
