Round Numbers to the Nearest 10 and 100 (Up to and Beyond 1000)

Example => 364 to the nearest 10 is 360, but 365 to the nearest 10 is 370.

To round a number to the nearest 100, check the tens digit to decide whether to round up or down. If the tens are 50 or more, round up. If they are 49 or less, round down.

Example => 1449 to the nearest 100 is 1400, but 1450 to the nearest 100 is 1500.
