In my blog’s second part, I will introduce a new trick which would be amazing and interesting like the previous one. I hope that you all will enjoy this trick and could it in your future.
Before starting, i would like to thank to all my viewers and visitors for giving a good response to my first blog. I hope that you do the same with this one.
Multiplication of those numbers in which the sum of the one’s digits is 10 and of the same ten’s digit;-
Multiplication of 45 & 45
45*45=2025
The steps of this trick are as follows;-
i) In the number 45, separate the numbers 4 & 5
ii) We will start from the right hand side. After 4 comes 5, so will multiply 4 by 5 and write the answer as 20_
iii) Next, we multiply the last numbers, i.e., (5*5) and write down 25 to the right of 20 and complete our multiplication.
Hence, our answer is 2025.
We can take more examples like:-
15*15=225 103*107=11021
85*85=7225 72*78=5616
66*64=4224 23*27=621
51*59=3009 84*86=7224
