How to ADD faster….????

This method will help you to add faster in mind between difficult calculations.

Always keep 5 and 10 as your adding reference .Mostly multiples of 10.This is so because it is easy to add or subtract 5 or 10 compared to any other numbers.It also helps to calculate orally.Here first I  will show adding numbers with some easier examples which you may already know.

Try to grab the method  rather than considering the silliness of the addition.

50+83=133… (50+50+30+3)  ; keeping multiples of 10 as reference as far as possible.Try to part your addition in multiple sections where each section would give easier number for the next addition to proceed.

This could be followed for bigger numbers also,

7592 +1351 = 8943 ….(7000+1000=8000; 8000+(500+300)=8800; 8800 + 100+41+2) = 8943

In the last underlined step.I was suppose to add (92 + 51) to 8800.Even for this small calculation i tried to reach the nearest and easiest reference i.e. 100. For this first i added 2 to 51 which gave 53.The two i added was the 2 from 92.Doing this, what now remains is    (90 +53 ) for the last part of the calculation.You will notice  now it is much easier to reach the reference 100. i.e (just add 10 borrowing from 53).so for the last part what remains is 100+43 which is 143.And adding 143 to 8800 is not a big deal with the same process again.

REMEMBER ALL THIS SORT OF CALCULATION IS TO BE DONE IN MIND.NO PEN IS NEEDED TO BE TOUCHED.

This may seem difficult for the first few times.But practicing this kind of method will really increase the speed of adding.The old method i.e. adding first the unit digits then the ten’s digits and so on will surely waste your time.

Practice it with your friend.Take any random addition and you add it with this technique while make your friend add it with the normal method.Practice till you win with a big margin of time.

Same can be done for subtraction.It will be posted later in subtraction category.
