Hello! Rounding a number can go up or down! If the second number is under 5, then it rounds down. For example: 23 it would round down to 22. If it were 25, it would round up because it is 5+ so it would be 26. So, you could do 29 which is above 5, which rounds to 30. And you could do 31! Which rounds down to 30 because it us under 5!
I hope this helped!
I am, yours most sincerely,
