"Rounding down" means that the number after the one you're looking at is less than five - or less than half of the distance to the next place in the whole number (since each digit is one unit of ten). You don't actually go down - you just leave the number the way it is instead of adding one to it the way you do when you "round up."Let's look at an example. Say you have 542 and you want to round it to the tens place. That means you're looking at the number 4 because it's in the tens place. Look at the number after that - see how it is less than 5? That means you "round down" to 540. You just leave the 4 as it is. If you had 547 you would "round up" to 550.
