Недавно мы обсуждали задачи на доказательства с использованием метода математической индукции для старших классов. Сегодня, как и обещали, мы предлагаем вам подборку задач на математическую индукцию, доступных для школьников средней школы.
📚 Следующая подборка задач будет особенно полезна для учеников 7-9 классов:

The S&P 500 fell 1.3% to 4,204.36, and the Dow Jones Industrial Average was down 0.7% to 32,943.33. The Dow posted a fifth straight weekly loss — its longest losing streak since 2019.

The Security Service of Ukraine said in a tweet that it was able to effectively target Russian convoys near Kyiv because of messages sent to an official Telegram bot account called "STOP Russian War." Perpetrators of such fraud use various marketing techniques to attract subscribers on their social media channels. Emerson Brooking, a disinformation expert at the Atlantic Council's Digital Forensic Research Lab, said: "Back in the Wild West period of content moderation, like 2014 or 2015, maybe they could have gotten away with it, but it stands in marked contrast with how other companies run themselves today." But Telegram says people want to keep their chat history when they get a new phone, and they like having a data backup that will sync their chats across multiple devices.

But it has "disclosed 0 bytes of user data to third parties, including governments," Telegram states on its website.
