We do not rewrite the text of the task e.g. "Bike price after discount...". We enter tasks using equations, inequalities, or other mathematical notation. In most tasks, it is given directly and you only need to rewrite them. You will receive a collection of 134 tasks from the last years in mathematics baccalaureate, so you can easily learn how to solve any task.

No. The calculator solves any task. By changing the numbers in the task, we will receive a different result. The given set of tasks serves only to get acquainted with the way (scheme) of solving the tasks.

Send me a photo of the task (MMS, e-mail or contact form) and I will show you how to enter it and solve it.

Entering letters is in the style of phones without a touchscreen: key 2 is abc, key 3 is def, etc. As you enter, a helpful map of keys is displayed on the screen – what which key means. In the user manual, you will get a detailed description of how to enter every possible letter, number or special character. After reading it and using the calculator for a short time, you will quickly write any text.

Yes, the calculator looks simple on all sides. The memory card, SIM card, microUSB port and LEDs indicating the charging status are invisible because they are placed under a screwed flap on the back.

I got stressed and pressed the keys to relieve myself.

It is not possible. Physically there is no speaker, microphone, camera, etc.

You won't see it. Notification of a new message will be displayed only after entering the secret unlock number.

The call will be automatically rejected. No sound or information comes out. Operation of all functions will remain intact.

The calculator has a really good antenna. During tests (in the forest), when it showed 1/9 signal strength in the settings menu – it also worked very well. If there is really no signal, everything that does not require communication will work (simple calculator, content from the memory card, SMS history, settings). Before entering the secret unlock number for the first time, the modem is not powered, does not send any signal, and does not try to log into the GSM network. Moreover, any jamming/interference of the signal of public telecommunications networks is prohibited (at least in Poland).

It is not possible. The firmware is really well written and tested. In an extreme situation, the built-in Watchdog timer will work, which will automatically turn off the calculator after a few seconds and you can turn it on again.

No, there are no hidden or additional fees. The only cost you will incur is the cost of purchasing the calculator and the possible top-up of the SIM card from the operator (fee for data transfer or sent SMS).

Yes.

No.

Purchase only.

Unfortunately, not because of the taxes paid (company), but nothing prevents you from selling to someone else (private person).
