Study Notes

Place Value in Mathematics

  • Place value is the value of a digit in a number based on its position or place in the number.
  • It is the value of a digit in a number that depends on its location.

Determining Place Value in a Number

  • In a number, each digit has a place value based on its position, starting from the right: units/hundreds, tens, hundreds, thousands, and so on.

Example of Place Value

  • In the number 456, the place value of each digit is:
    • 4 (hundreds place): 4 x 100 = 400
    • 5 (tens place): 5 x 10 = 50
    • 6 (units place): 6 x 1 = 6

Place Value Chart

  • A place value chart is a table that displays the place value of each digit in a number, from right to left.
  • It is useful for:
    • Visualizing the place value of each digit
    • Understanding the relationship between digits in a number
    • Performing calculations and operations on numbers

Change in Place Value

  • As you move left on the place value chart, the place value of a digit increases by a factor of 10.
  • As you move right on the place value chart, the place value of a digit decreases by a factor of 10.
  • This means that the place value of a digit changes exponentially as you move left or right on the chart.
