We 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.
