                    Can you help Ashu in the calculation?

                    1.  The next day, her mother makes 69 more rakhis. So, she has a total
                                + 69 =        rakhis for sale.

                    2.  At the end of the day, 10 rakhis are left. That means,                     – 10 =         rakhis
                        were sold on that day.

                  SUBTRACTION FACTS

                  We know that ‘taking away’ is subtraction.

                  Krish has blown 9 balloons. 6 of them burst out.                  9

                  How many balloons are left now?                               –   6

                  Here, we subtract 6 from 9. Our answer is 3.                      3        Difference

                  The sign of subtraction is ‘–’ (minus).

                  So,                         9     –     6     =     3    Subtraction fact

                    The answer of subtraction is called the difference.

                    The number from which we subtract another number is called minuend.

                    The number that is subtracted from the first number is called subtrahend.
                  Properties of Subtraction

                  Subtracting 0

                  When we subtract 0 from a number, the difference is the number itself.

                  (a)  15 – 0 = 15         (b)  72 – 0 = 72          (c) 26 – 0 = 26

                  Subtracting 1

                  When we subtract 1 from a number, the
                  difference is the number that comes just                          Knowledge Desk

                  ‘before’ the subtracting number (Minuend).                      The word “subtraction” is made up of
                                                                                  two words ‘sub’ and ‘tract’. ‘sub’ means
                  (a)  26 – 1 = 25         (b)  60 – 1 = 59                       below or bottom and ‘tract’ means to
                                                                                  carry away. Then, ‘subtraction’, means
                           before                  before                         ‘to carry away the bottom part’.
