Think of a number, any number.
Double it. Add 26 to it.Half it.
Then take the original number you thought of, away from it....You are left with 13.

That's right ! Amazing .. it also works with bigger numbers - I tried with 432.
It doubling and halving and then 26 must have something to do with it - I am not mathematician ...absolutely anything do with numbers baffles me
Fun !

I tried it with 1,798,493 and the wee adding machine gave up, or, maybe the answer 0.96 is right.

As an apology, here is another one:
* Choose a Number
* Add 5
* Double the result
* Subtract 4
* Divide the result by 2
* Subtract the number you started with
* The result is 3 -
13 * 2 = 26
