In the case I would first write ALL factors of 600 and find the differences.
1x600
2x300
3x200
4x150
5x120
6x100
8x75
10x60
12x50
15x40
20x30
24x25
The one that subtracts to give the answer is -20 and 30
When rounding from the ten's place, the numbers above 600 and below 605 round down to 600. When rounding from the hundred's place, the numbers above 600 and below 650 round down to 600. Since 600<1000, we cannot round from the thousand's place. So the numbers above 600 and below 650 round to 600.

Since the number is 631, and you want to round it to the hundred's place, you have to look at the ten's place. The number in the ten's place is 3, so you round down. The rules are rounding are: 1. numbers 1~4 round down 2. numbers 5~9 round up This number, 631, would round to 600.
600 ten thousands = 600,00
ten minutes is 600 seconds
