Connecting Math to Our Lives Report Vedic Mathematics Bangalore, INDIA: Vedic Mathematics I am B.N. Bhaskar, Maths teacher, Vikasa High School,Ramamurthy Nagar,Bangalore-16. I have studied Vedic Mathematics to some extent and I am teaching easy methods of it to my students. I came to know that Swamy Bharathi krishna thirtha Maharaj, Shankaracharya of Puri has written 16 simple Suthras for different calculations. I. Finding the Square of a Number Ending with 5 To find the square of a number ending with five, it is very easy. eg. To find the square of 35 The answer contains 2 parts. The first part is 3(3+1)=3x4=12 The second part is 5 square i.e 25 The final answer is 1225 Similarly, Square of 45 is 4x5=20 and 5x5=25 i.e 2025 II.Squaring Numbers Sutra: Yaavadunam Taavaduunikruthya vargam cha yogayet Meaning: Whatever the extent of its deficiency, lessen it further to that very extent; and also set up the square of that deficiency. This sutra is a corollary of the Nikhilam sutra. Consider a simple example 92 Step 1 : Consider the nearest base (here 10). Step 2 : As 9 has a deficiency of 1 (10 - 9 = 1), we should decrease it further by 1, and set down our L HS of the Answer as '8'. Step 3 : On the R HS put the square of the deficiency (here 1). We get 92 = 81. Try 8 square III. Multiplication Let's multiply 102 and 102 The two numbers are close to 100. So, let the base be 100. 102 is 2 more than 100 and 103 is 3 more than 100. 102....+2 103....+3 ------------- The answer has 2 parts The first part is 102+3 = 103+2 =105 The second part is the product of 2 and 3 =06 Therefore, 102 x 103 = 10506 Try 104 x 105
