The value of a digit in a number depends on its place value. In the number 243, the 2 is in the hundreds place so it represents 2 hundreds or 200. The 4 is in the tens place so it represents 4 tens or 40. The 3 is in the ones place so it represents 3 ones or 3. Together 243 represents 2 hundreds + 4 tens + 3 ones, or 200 + 40 + 3, which equals 243.
