To compare two whole numbers, compare

the digits in each place from left to right.

Compare the digits in each place from left to right.

Start with the hundreds place.

2 = 2

The digits in the hundreds place are equal, so compare the digits in the tens place.

4 = 4

The digits in the tens place are equal, so compare the digits in the ones place.

2 < 3

Since 2 < 3, 242 < 243.
