       11th Lesson of  mathematics tricks and fun       Hello friends ,today we are going to stud y Nikhilam Sutra in multiplication. I am Dr Prema b sejekan.  Nikhilam Sutra says Nikhilam Navatascharamam Dasatah.Means All from Nine and Last from Ten . Nikhilam sutra has upasutras corollaries and sub-corollaries.All of them and their application  in multiplication will be discussed here.  Here  applications of Nikhilam Sutra in general is shown.Let us take the first among the 7 examples. In this, the first question is  9 times 9.working base is 10 . So complement of 9 from 10 is 1.   1×1 is 1 and  9-1 is 8. The answer is 81.2nd example is 7× 6 , so complement of  7 from 10 is 3. Complement of 6 is 4 so we will write 7-3× by 6-4 so ,3×4 is 12 and 7-4,is 3 .Adding the carry overs answer is 42.  Rest all examples are with different bases ie  100,1000 base  done in the similar way. ...

9th Lesson mathematics Tricks and Fun Hello friends , I am Dr Prema B Sejekan In this we are going to recapitulate the various methods available to us in the squaring of numbers by Vedic Mathematics. First we will practice again the squaring of numbers with same digits using the special code . What is the special code?“One more, one less. . Examples given are. - square of ”9999   9× 9 = 81. We will place 8 on unit place on multiplicand side and 1 on unit place on multiplier side.***8 ***1Now one more than 8 is 9 so three 9 s beside 8 and one !ess than 1 is 0. So three zeroes beside 1.Answer is 99980001 Same way square of 3333 , ,3×3 is 09 So***0 ***9.o nemore than0 is 1 and 1 less than 9 is 8 final answer is 11108889 Square of 6666 - 6×6= 36 .we arrange as said earlier ***3 ***6. One more than 3 is 4 and OneLess than6 is 5 so final answer is 444355556 Using the arithmetic progression method from both sides .count the digits first. Totally 10 digits. . 1×1 is 01 In...
