Banks–Zaks fixed point
Do you know what a piggy bank is? It's a container where you put your coins to save them, right? Now, imagine a bank is like a piggy bank, but for grown-ups. People put their money in a bank to keep it safe and let it grow.
Now, let's talk about something called the "Banks-Zaks fixed point." It's a fancy way of saying that if you keep putting money in a bank account that earns interest, there will be a point where the amount of interest you earn is equal to the amount of money you put in.
Let's use an example. Say you have a bank account that earns 10% interest every year. If you put $100 in that account, at the end of the first year, you'll have $110 (the original $100 plus $10 in interest). If you leave that money in the account for another year, at the end of the second year, you'll have $121 ($110 plus $11 in interest).
If you keep leaving the money in the account and earning interest, there will be a point where the amount of interest you earn in a year is equal to the amount of money you put in. In this example, that would happen when you have $1,000 in the account. After that, you'll earn $100 in interest every year (because 10% of $1,000 is $100), and your account balance will stay the same.
That point where the interest you earn equals the amount you put in is called the Banks-Zaks fixed point. It's an important concept because it means that if you keep saving and earning interest, you can reach a point where your money is working for you without you having to do anything. Pretty cool, huh?
