First of all, square any two digits and ends in five, here goes: Let’s take an example the number 25**2 , what are you going to do is take the first number(2) and multiply it with one more than that which means (3), so you’ll six(6) right.

Now save that number and go to the next number (5) just do the normal operation of squaring it, so you’ll have 5*5 which equal to 25.

After that put the result in a raw and you’ll get 625.

And you can go to your friend or someone you know and give him a paper and a pen, and ask him to square two digits ends in five, and tell him I’m going to do it in my mind.

And the moment he/she tries to solve the problem you already answered it in your mind, when you bombard him with the answer, he’ll be shocked with the result when he’ll finish.

He’ll ask you how did you do that.

So you can tell him it’s not a big deal, I do that in my mind, he definitely will think you’re a brilliant.

However, when he’ll insist to know it, and you tell him about it, he probably will look you in the face and say: Get out here, because it lost its magic once it’s been revealed.

I hope you enjoyed it 
