Each number has a place value. It determines the value of that digit according to its position in the number. The value of a digit in a number increases as we move from left to right. The digits on the left have lower place value than the digits on the right.

  • Expanded form is not same as expanded notation.  The expanded notation a number is represented as the sum of each digit in a number multiplied by its place value. 

    Expanded form: 234 = 200 + 30 + 4

    Expanded notation: 234 = (2  100) + (3  10) + (4  1)

    In the expanded forms, we use only addition between the place value numbers and in the expanded notation we use addition and multiplication.
