Ah, the sounds of School House rock teaching us the rules of rounding. When we're being asked to round any number we must identify the place value to which we're rounding in the number.
In our case, we want to round 9,999 to the nearest hundreds place value. Hundreds come before thousands so we're looking here: 9,999. Now we need to focus our attention here: 9,999. Is this number 5 or greater? Yes, we round up. Therefore, the nearest hundred to 9,999 is 10,000.
If the number had been 9,499 we would follow the same steps. The hundreds place is a 4 and the place directly next to it is greater than a 5, we round up. 9,500. Had it been 9434, we would round down to 9400.
9999 rounded to the nearest tens place is 10,000
