Can you multiply 23 with 27 or 79 with 77 without using pen and paper or a calculator? Second question: Can you multiply 23 with 27 or 79 with 77 using pen and paper without using the three line method? It is possible only if you know how to do calculations using methods of Vedic mathematics.
Punjab education department has started imparting training in Vedic maths to teachers of government schools in the state. In the first phase, a six-day seminar was organised in Chandigarh in October for resource persons from all the districts of Punjab. Now, the resource persons are training maths teachers in their respective districts.
A manual of Vedic mathematics, comprising basic principles, has been distributed to the teachers for their convenience.
“Though there is no plan to make it compulsory for the students to learn Vedic maths, the department has started training teachers to create awareness about it,” said an official of the department.
“We teach multiplication tables without telling students why 2 by 2 is four. What is the logic behind it and why it is 4 and not 5? But Vedic mathematics explains its reason,” said Dharampal, a mathematics teacher at Patara government school.
Students usually cram multiplication tables up to 10 or 20 with great difficulty but with the help of Vedic maths, they can learn tables up to 99 with ease, he further added.
Further elaborating characteristics of Vedic maths, he explained, “Normally when you multiply 23 with 17, you first multiply 23 with 7, then 23 with 1 and in the third line, you make the total of the two lines. In Vedic maths, multiplying 23 with 17 is just one line and it is simpler without using paper and pen or calculator. Unnecessary dependence on calculators will automatically decrease by using these techniques.”
