                  Subtraction of a number from Itself

                  When a number is subtracted from itself, we get 0 as the difference.

                  Examples:  (a) 26 – 26 = 0          (b) 324 – 324 = 0  (c) 1248 – 1248 = 0

                  Subtracting 10, 100 and 1000

                  Subtracting 10 from a number

                  When we subtract 10 from a given number, we subtract 1 from the digit at the tens place
                  and ones digit remain the same.

                  Examples:  (a) 57 – 10 = 47  (b) 493 – 10 = 483                  (c) 1619 – 10 = 1609

                  Subtracting 100 from a number

                  When we subtract 100 from a given number, we subtract 1 from the digit at the hundreds
                  place and tens and ones digits remain the same.

                  Examples:  (a) 295 – 100 = 195             (b) 587 – 100 = 487          (c) 2699 – 100 = 2599

                  Subtracting 1000 from a number

                  When we subtract 1000 from a given number, we subtract 1 from the digit at the
                  thousands place and hundreds, tens and ones digits remain the same.

                  Examples:  (a) 9397 – 1000 = 8397 (b) 2695 – 1000 = 1695

                           Think and Answer
                        1. If 1000 – 9 = 991, then what is 9000 – 9?
                        2. What is the difference between 723 tens and 7 thousands 23 tens?

                  1.  Fill in the blanks using subtraction properties.

                       (a)  273 – 0 = ______            (b)  564 – ______ = 564          (c)  7364 – 0 = ______

                       (d)  575 – 1 = ______            (e)  649 – ______ = 648           (f)  ______ – 1 = 276

                  2.  Subtract the following.

                       (a)  425 – 10                    (b)  896 – 10                    (c)  567 – 100

                       (d)  4364 – 100                  (e)  2645 – 1000                  (f)  5730 – 1000
