What Calculator does
This is the most stripped-down entry in the list: there is no /start ceremony, no inline mode, no menu. You open the chat, type a math expression such as 2+210 or (12+8)/43, and the bot replies with the computed number. It handles the four basic operators and parentheses correctly, respecting order of operations, which covers the vast majority of quick "what's this number" moments people actually have during the day.
What sets it apart from the many near-identical calculator bots on Telegram is usage: its public profile shows close to 30,000 monthly users, which is a meaningfully larger audience than most of the alternatives in this category, most of which show no visible usage figures at all. That kind of sustained traffic is a reasonable proxy for "this bot has kept working reliably for a while," since a broken bot tends to bleed users fast.
It is deliberately narrow, though. There are no scientific functions such as sine or square root, no unit conversion, and no documented behavior inside group chats — for either of those you will want a different bot from this list. Think of it as the fastest possible four-function calculator you can drop into any conversation, not a do-everything math tool.
How to start

FAQ
Do I need to send a command first?
No, just type the expression and send it directly.
Can it do trigonometry or square roots?
No, only the four basic operators and parentheses; try mathcalcbot for functions like sin and sqrt.
