Tens place = 1 × 10 = 10 -bzsf] :yfgdf ! Ö !)_
Hundreds place = 2 × 100 = 200 -;osf] :yfgdf @ Ö @))_

Again, let's take any two numbers 3405 and 16072.

3 4 0 5
Ones place = 5 × 1 = 5 -Pssf] :yfgdf % Ö %_
Tens place = 0 × 10 = 0 -bzsf] :yfgdf ) Ö )_
Hundreds place = 4 × 100 = 400 -;osf] :yfgdf $ Ö $))_
Thousands place = 3 × 1000 = 3000 -xhf/sf] :yfgdf # Ö #)))_

1 6 0 7 2
Ones place = 2 × 1 = 2 -Pssf] :yfgdf @ Ö @_
Tens place = 7 × 10 = 70 -bzsf] :yfgdf & Ö &)_
Hundreds place = 0 × 100 = 0 -;osf] :yfgdf ) Ö )_
Thousands place = 6 × 1000 = 6000 -xhf/sf] :yfgdf ^ Ö ^)))_
Ten-thousands place=1×10000=10000 -bz xhf/sf] :yfgdf !Ö!))))_

The face value of each digit of any number is the digit itself.
For example, the face value of 6 in 16072 is 6. The face value of 9 in 28914
is 9, and so on.
1.5 Expanded forms of numbers

Let's learn about the expanded forms of numbers from the given illustrations.

45 =

= 4 × 10 + 5 × 1
4 × 10 5 × 1

236 =

= 2 × 100 + 3 × 10 + 6 × 1
2 × 100 3 × 10 6 × 1

3104 =

= 3 × 1000 + 1 × 100 + 4 × 1
3 × 1000 1 × 100 4 × 1
