Let me share an incident that happened to me when I was in school.
Before the examination started at the school examination hall, one of my friends asked, “can I borrow your calculator during the mathematics examination?” He had a battery-powered calculator but the battery was dead and he was unable to replace the battery.
His seat was just behind me, so I agreed to his request.
Unfortunately, during the examination, I was too busy with different calculations. I had to look for answers to many mathematics questions, and without my calculator, it was quite impossible to answer the questions correctly.
I shared my basic calculator with my friend as promised, but I was losing my concentration every time since I had to ask for my calculator from him, and he was asking for the calculator quite frequently. The truth is I was feeling disturbed too.
However, even with this problem, I finished my examination quite perfectly.
After the examination, I advised my friend, saying, “A good calculator can save both of our valuable time. A wide range of best solar-powered calculators are available in the market. Why don’t you buy one?”
The good news was; he took a new basic solar-powered calculator in the next examination.
I am the owner of a super-shop now. And from my school life to now, I do all my calculations using solar battery calculators. I used many different low-priced solar-powered calculators of different manufacturers named Casio, Helect, Eastpin, etc.
In this article, I will share reviews of the 10 best basic calculators available at an affordable price. To know about other top rated calculators, please read this review.

Portability: Ask yourself, do you need a calculator that will be sitting on a desk or office for a whole day, or will you need to carry it from one class to another?

Power Source: The truth is, many customers look for a solar-powered desktop calculator that doesn’t come with battery-powered features also. It is because you can keep yourself worry-free since changing the battery is unnecessary in these calculators.
