Addition of Three Numbers





                         Kriti, you want 2 cookies and Ricky wants 3.





                                                            Yes mamma, we want 5 cookies.






                         I also want to eat 2 cookies. How many
                         cookies should I get now?





                                               2 cookies + 3 cookies + 2 cookies = 7 cookies




                   Kriti              Ricky             Mother                          Total





                             +                       +               =






                     2       +           3           +       2       =                    7

                2 + 3 + 2 = 7 is read as ‘2 plus 3 plus 2 equals 7’.



              9   Add and write.



              (a)                            +                     +                             =






              (b)            +                                         +                         =





              (c)                               +              +                                 =
