Expanded Notation and Written Form

Expanded notation is a way of writing numbers to show the value of each digit. For example, the number 345 can be written as (3 x 100) + (4 x 10) + (5 x 1).

To convert expanded notation to standard form, you add the values together. For example, (3 x 100) + (4 x 10) + (5 x 1) = 300 + 40 + 5 = 345.

The standard form is 53.8.

(7 x 100) + (2 x 10) + (1 x 1) + (3 x 0.1) + (9 x 0.01).

In the number 3,482, the digit '3' represents 3,000 because it is in the thousands place.

0.437 can be written as (4 x 0.1) + (3 x 0.01) + (7 x 0.001).

In the number 654.86, the digit '6' represents 600 because it is in the hundreds place.

The standard form is 0.437.

(3 x 10) + (6 x 1) + (8 x 0.1) + (0 x 0.01) + (2 x 0.001).

86 can be expressed as (8 x 10) + (6 x 1).
