Math Problem Statement

Place value

Solution

Place value refers to the value of a digit depending on its position in a number. In our base-10 number system, each place represents a power of 10, with the value increasing as we move from right to left.

For example, consider the number 4,836:

  • The digit 6 is in the ones place, so its value is 6 × 1 = 6.
  • The digit 3 is in the tens place, so its value is 3 × 10 = 30.
  • The digit 8 is in the hundreds place, so its value is 8 × 100 = 800.
  • The digit 4 is in the thousands place, so its value is 4 × 1,000 = 4,000.

Thus, the value of each digit is determined by its position.
