The day before yesterday, I also bought a small book about abacus.
I've been wished to learn abacus for a long time.
I once learned it for about one month when I was in Grade 2, but I had to quite the after school because of moving. Then, after that I didn't go any such school for abacus.
But now, with this book, I can learn to calculate all of these: addition, subtraction, multiplication and division.
It's said that if someone trains really hard, the person can have a marvelous calculation ability such that he/she can perform more than 5 figures of addition or subtraction really quickly in his/her head. (Of course such person can do multiplication and division at sight too.)
But I, at least, want to be able to perform addition and subtraction of 3 figures in my head.

I've had abacuses (that may not be the right plural) come into my life a couple times, and always thought I should learn how to use them, but never did. I have, like you, heard that people who know how to use them can do many sorts of mathematical things quickly and accurately.
I'm afraid I'm pretty shallow: I think they are pretty things, whatever their usefulness.
You have written this very well, Saku. I'd leave out the "been" in the sentence about how you have wished to learn the abacus, and maybe I'd put a colon before the list of things you could do, like this: "I can learn to calculate all of these:"
I try not to use the little electric or electronic calculators too much, myself, so that I can keep remembering how to do math. It was never my best subject.
