Squaring a number ending with 5
Learning Vedic Mathematics short cut methods is a useful way for improving mental mathematics ability of children.
By watching the given video you can learn a short cut method to find the square of a number ending with 5 using the sutra
This means "By one more than the previous one".
I am sharing one example how this sutra is applied?
65^2= [6 X (6+1)] 25 = 4225
For this number , the last digit is 5 and the 'previous' digit is 6. Hence, 'one more than the previous one', that is, 6+1=7.
The Sutra, in this context, gives the procedure 'to multiply the previous digit 6 by one more than itself, that is, by 7'. It becomes the L.H.S of the result, that is, 6 X 7 = 42.
The R.H.S of the result 25..
- Mathematics teacher since 1994. After joining teaching profession I realized two things. First one- there is so much which is still to be learned and the second one - there is no standard method for teaching .Each day a new challenge randomly comes forward . For overcoming, there is a need to explore, learn and change. I believe learning is not confined to the four walls of the classroom.Enormous tools are available on the web which may be utilised for making teaching/learning interesting and effective.For me teaching is not just a job,its a passion,a commitment...a mission.
