9 posts held, back to 14 October 2023 — the reader has not yet reached the start of this channel’s public history, so older posts may sit further back, unread. Read across 1 page of Telegram’s post history, 20 posts per page.
Nothing published in the last 30 days. ERR and ER are rolling 30-day measures, so there is nothing to compute — we hold 9 posts for this entry, the most recent from 10 March 2024. An engagement rate over an empty window would be a number about nothing.
Lifetime counters from Telegram’s own channel header, read 11 August 2026 — not the date at the top of this page, which is when the subscriber count was last read. Below Telegram’s rounding threshold, so these counts are exact.
4 reactions across 3 posts, in 3 distinct kinds. The most used accounts for 50.0% of them.
| Reaction | Count | Share | Share, drawn |
|---|---|---|---|
| 👀 | 2 | 50.0% | |
| 👍 | 1 | 25.0% | |
| 🔥 | 1 | 25.0% |
No sentiment is inferred, and none should be read in. This table is ordered by count and by nothing else. Emoji do not carry stable meaning across languages or communities — 🙏 is thanks in one channel and mourning in another — so we publish which ones were pressed and how often, and pass no judgement on what an audience meant by them.
Precision. Telegram publishes reaction counts per emoji and short-forms each one — 4.34K, 1.2M — so any single kind at or above 1,000 reaches us at three significant figures, and only counts below 1,000 are exact. The shares above are ratios of those figures and carry the same error. This is also why the total here can differ slightly from a reaction total printed elsewhere on the page: both are sums of the same rounded parts, taken over samples with different edges.
Coverage. Reactions were read on 4 of the 9 sampled posts in this sample. Summed by Telegram’s own count on each post — not by adding up the per-emoji breakdown above — those same posts carry 4 reactions in total: the kind of figure the paragraph above means by “a reaction total printed elsewhere on the page”.
Measured over the 9 most recent posts we hold, published 14 October 2023 to 10 March 2024, using the newest reading held for each. Telegram Stars are excluded: they are a payment, not a reaction, and they have their own section.
Что-то никто не решил задачу про молоко и кофе. Я придумал, как сделать условия более наглядными: Пусть у нас есть два стакана: в первом 1000 черных шариков, во втором — 1000 белых. Мы берём 100 белых шариков из второго стакана и помещаем в первый. Затем берём 100 шариков из первого стакана (среди них есть и черные, и белые) и помещаем во второй. В итоге в обоих стаканах снова по 1000 шариков. Вопрос: чего теперь бо…

Что не так на этой картинке? Сложность: 🐣
⚡ Про кофе и молоко ⚡ Сложность: 🤔 Есть два стакана. Первый с кофе, второй с молоком. Заполнены одинаково. Мы берем ложку молока из второго стакана и добавляем в первый. Перемешиваем. Потом берем ложку смеси из первого стакана и добавляем ее во второй. Чего теперь больше: молока в первом стакане или кофе во втором? Решать можно по-разному — интересно, какой способ выберете вы. * Никакого подвоха, связанного понят…
⚡ Неожиданная задача со спичками ⚡ Сложность: 🤔 Переложите одну спичку так, чтобы равенство стало верным.
⚡ Про лошадей и кузнецов ⚡ Сложность: 🤔 12 кузнецов должны подковать 15 лошадей. Каждый кузнец тратит на одну подкову 5 минут. Какое наименьшее время они должны потратить на работу? (Учтите, что подковать нужно все 4 ноги, а лошадь не может стоять на двух ногах.)

⚡ В Бронкс или Бруклин? ⚡ Сложность: 🤔 Один молодой человек живет в Манхэттене возле станции метро. У него есть две знакомые девушки. Одна из них живет в Бруклине, вторая — в Бронксе. Когда он едет к девушке из Бруклина, то садится в поезд, подходящий к платформе со стороны центра города. Когда же едет к девушке из Бронкса, то садится в поезд, идущий в центр. Поскольку обе девушки нравятся ему одинаково, он просто с…

⚡ Сколько же он весит? ⚡ Сложность: 🐣 Теннисный мяч весит 29 граммов плюс половина его веса. Сколько же это граммов? * В данном случае вес и масса это синонимы👀
Channel created
Showing the 9 most recent of 9 posts we hold for @clearmath. View and reaction counts are the latest single reading for each post, not a live figure, and a recent post is still accumulating both. A view count marked ≈ was rounded by Telegram before we ever saw it — t.me prints views in full below 1,000 and to three significant figures above, so ≈1,200,000 means somewhere between 1,150,000 and 1,249,999. Unmarked counts are exact. Text is reproduced from the public post preview and truncated for length.
Named by 1 registered channel — every channel on the register whose own posts have named this one, by its current username or any other username it currently holds, merged from two separately captured readings of the same fact so a namer caught by only one of them is not missed and a namer both caught is not counted twice. A username this channel has since dropped is not matched — that handle may belong to someone else now, and crediting today’s namer to yesterday’s owner would misattribute it.
Named by
Channels on the register whose posts name this channel's handle.
A mention is a weaker signal than a forward and is counted separately for that reason — naming a channel is not republishing it, and a handle in a post body is easy to place deliberately. The post counts beside each row below are distinct posts in which the handle appeared, from posts we have read on both sides — the “Named by N registered channels” figure above is a different count, of distinct NAMING CHANNELS rather than posts, and is not the sum of the rows under it.
A live page changes as we take new readings, so a citation should name the measurement it is based on, not just the URL. The line below cites the subscriber count as measured 11 August 2026 — this entry's latest reading, not the date you are reading this.
