When we round a number to the hundreds place we look to our tens place to tell us if we round up or down. If the number in our tens place is $\displaystyle 5$ or greater, we round up. If the number in the tens place is $\displaystyle 4$ or less, we round down. When we round up, the number in the hundreds place increases by $\displaystyle 1$ and all the other numbers become $\displaystyle 0$. When we round down, the number in the hundreds place stays the same and all the other numbers become $\displaystyle 0$.
