Why Do We Count Money in Different Ways Around the World?

Money is like a language that countries speak. Some say it with big numbers, and others say it with tiny ones. For example, in Japan, people often use coins for small things, while in the US, we mostly use paper bills. It all depends on what makes life easier for each country's people.

Countries pick how they count money based on their history and daily life. If a lot of people are used to counting by 10s or even 5s, that becomes the way they do it. Like when you're playing with blocks, some kids stack them in groups of 5, others in groups of 10.
