              exPaNDeD Form oF a Number

              Expanded form of a number means expressing the given number as the sum of  the place
              value of its each digit.

              example:       th H t O
                             4 5 8 9
                                             9 ones = 9 × 1 = 9                       Expanded form of 4589 is

                                             8 tens = 8 × 10 = 80                     4000 + 500 + 80 + 9.
                                             5 hundreds = 5 × 100 = 500
                                             4 thousands = 4 × 1000 = 4000


              short Form


              When we write a number using digits (0, 1, 2, 3, ..., 9), keeping in mind its place value,
              the number is said to be in short form.
              example:  7000 + 500 + 80 + 4 = 7 × 1000 + 5 × 100 + 8 × 10 + 4 × 1

                             = 7 thousands + 5 hundreds + 8 tens + 4 ones               7584 = 7000 + 500 + 80 + 4

                             = 7584                                                     Short          Expanded

                                                                                        form             form

              1.  In the given numbers, write the place value of each digit in blank boxes.

                   (a)    6 3 2 9                    (b) 1 5 0 8                     (c)   4 9 8 0









              2.  Write the face value and the place value of the underlined digits.

                   (a)  1234                        (b)  7851                        (c)  9802
                        Face value: _______              Face value: _______              Face value: _______

                        Place value: _______             Place value: _______             Place value: _______

              3.  Fill in the blanks.

                   (a)  6,375 = 6,000 + _____ + 70 + _____
                   (b)  5,082 = ______ + 0 + _____ + 2

                   (c)  8,421 = 8 thousands + _____ hundreds + _____ tens + 1 one

                   (d)  4,095 = ___ thousands + ____ hundreds + 9 tens + ____ ones
