People like round numbers because they’re easier to understand. Round numbers are like 10, 100, or 1000, they feel simple and neat. Think of it like counting on your fingers: when you get to 10, it feels like a new group starts. So instead of saying ‘I have 27 apples’, we might say ‘I have about 30 apples.’ It helps our brains simplify things.
Examples
- When you're counting toys, you might say ‘I have about 20 blocks’ instead of ‘I have 17 blocks.’
- If a pizza costs $9.85, you might think it's about $10.
- You might say there are about 50 people at the party even if there are actually 47 people.
