First thing is to memorize squares upto 25. Schools generally hammer these into your brain, so that's a reasonable requirement I guess.
Suppose the number is between 25 and 50. Let's express it as 25+n, 25>n>0. Get the square of 25-n (now that you remember it). Take it and add 100n. Voila.
Let's take an example. Suppose you want to square 43.
25-18=7 whose square is 49. add 100n=18*100=1800 to it.
Answer is 1849.
Next step. Suppose the number lies between 50 and 100. Let's say 73.
So let's first find square of 50-n=27.
27 lies between 0 and 50 so you can use the trick mentioned above to find it if necessay.
Anyway it is 729.
Add to that 200n=4600. So 4600+729=5329, the required answer.
Note here we multiplied by 200 (as 'base' is 50, not 25), rest is same.
You can go on for x=100+n but then the amount of backtracking takes a little longer. And you have to multiply by 400.
The explanation of why this works is pretty simple, but it will be lengthy (in fact I started this post with it, but it just kept growing, and not to mention blogger is terrible with formatting), so I'll skip it.

There are things that touch your soul in ways you can't describe. Watching 'The man from earth' had that effect today. And not for the first time. What moves you is the crux of your identity, and as it gets overpowered by the dross of everyday life, it felt really good to glimpse it once more.

Now about the strangeness. In this world, time has reversed itself, something called the Hobart Phase. The dead reform in their coffins, and knock and ask to be let out. There are businesses doing just that, selling the deaders (as they are called) to the highest bidder. People say 'Goodbye' when they pickup the phone, 'Hello' just before they hangup. 'Smoking' cigarette butts converts them to full length cigarettes. A religious leader is about to be reborn, and the story revolves around the consequences.
Despite the strangeness, the plot is quite plausibly developed and the narrative is fast paced. A good read, but probably only for 'serious' readers (but don't ask me to define that).
