Finding out the square of any number in seconds

Saturday, December 19th, 2009

square-root-in-secondsWe cannot imagine the world without calculations i.e, Mathematics. It is present in all phases of  our life. Irrespective of our background or discipline we use it. Now i am going to share with you a small short cut for fast calculation. It is highly useful for the students. Particularly those who are preparing themselves for competitive exam.

Finding out the  square of any number in just 20 seconds.

For example let us take 23 and we will find out the square for this number in the easiest and quickest way.

STEPS

A.  First reduce the number’s unit digit to zero. In this case it is 20. Now the unit digit is zero or we can simply subtract

3 from 23 it comes to 20.

B. Now we should add back that 3 to 23. The total comes as 26. So we should subtract and add only once.

C. In the third step you will multiply the 2 numbers i.e, 20 and 26. Multiplication of these numbers is 520.

D. Finally we should take the square of digit 3, which we have subtracted first and added again, that is 9.

and should add them 520+9= 529.

Let us take 35 as one more example.

35-5 = 30  and 35+5 = 40

30*40 = 1200

5*5 = 25

1200+25 = 1225.

We hope you have enjoyed this trick. Check our other trick on Vedic Mathematics multiplication.

INNOVATION V/S INVENTION

Tuesday, October 27th, 2009

imagesDo you know why the technology product life cycles are measured only in months? Why are some of their amazing features almost be impossible to use?

Let us consider the mobile phones. Have you ever tried to use the acclaimed web browsing feature from a cell phone or tried to plug it in your notebook? Or ever counted how many clicks n commands it takes to access any function on your cell phone? Ever have you made a “conference call”? Even if you know that this feature exists. Don’t you?

Ok let us take the case of cameras. Many of us are using multi-million pixel cameras. Once you are back from your vacation, how do you sort the pictures? How do you actually know what a picture contains in which all the file names are given cryptic numbers? Trust to arrange them and make an album of them? If you are using a much vaunted camera phone, should it not be easier to download these pictures directly to a wire free device that can make prints for you?
Even though Printing is an easier task how difficult can it be to print address labels in fabulous 300-dpi colors’ at 10pages per minute? But wait. If you want to print directly on envelopes using Microsoft outlooks contact list, you cannot do it unless you first create a mail merge document a task as easy and enjoyable as changing the spark plugs on your car every time you want to start it.

The lesson is that while hardware and software technology companies are far more sophisticated today than they were a decade ago, they have been so busy. Inventing that they have not paid enough attention to “INNOVATION”.

Innovation is the process of applying ingenious ideas to great inventions so that they become usable by normal people like us. For example when Timberness Lee invented the internet. It was largely useless to most of us till innovators like MarkAndressen of Netscape. LeryYang of Yahoo! And designs of others created applications that opened doors to this brand new world. It was the “INNOVATIVE” adaptation of a simple hard drive technology that brought us the i pod.
So let us hope that this coming decade is one where innovation finally overtakes invention
