calculator

I purchased my own calculator.
It cost me £25, equivalent to 5000en.

Before I was using cheaper one and I think cheap ones and expensive ones do not make much difference.
I find a book explaining how to use a calculator. Before I thought, calculators are just calculator and we do not need to know much about it. They have simple interfaces and the buttons are not much, aren't they?!
I needed to know some. Now I think.
My calculator looks so cool and I am so in love with it.

What is so special about my calculator?!
Firstly, it have just fitting size to my hands. My hands are not so big and at the same time not so mall as well. I fond the just my size one.
Secondly the buttons were so special.
The numbers on the button never disappeared after even if I use many years since the number was not just printed on the buttons but made from the plastic itself.
The buttons have different curves depending on the row which they are allocated.
Some are concave and some are incarve on their top surfaces so that I can guess which number I am touching without seeing them.
Thirdly I choose a Kashio calculator. There are two major calculator makers, Kashio and sharp.
They have different interface and the their calculators are operated in different ways.

I put a mark on it so that people can see it is mine.
