Common Mistakes

MISTAKE: Confusing 'exactly 5' with 'around 5' or 'about 5'. | CORRECTION: 'Exactly 5' means precisely that number, no approximation. 'Around 5' could mean 4, 5, or 6.

MISTAKE: Thinking 'exactly 5' means 'at least 5'. | CORRECTION: 'At least 5' means 5 or more (like 5, 6, 7...). 'Exactly 5' means only 5.

MISTAKE: Not counting carefully and misidentifying a group of 4 or 6 as 'exactly 5'. | CORRECTION: Always count items one by one to ensure you reach the specific number five.
