                9.  Observe the pattern, and write the next two steps.
                    (a)     8 + 1           = 9                      (b)     1 × 9        + 2       = 11

                           80 + 10          = 90                            12 × 9        + 3       = 111
                         800 + 100          = 900                         123 × 9         + 4       = 1111

                         ___ + ___          = ___                         ___ × ___ + ___ = ___
                         ___ + ___          = ___                         ___ × ___ + ___ = ___



                    (c)     3 × 3           = 9                      (d)      24 ÷        8    = 3

                           33 × 3           = 99                            240 ÷         8    = 30

                         333 × 3            = 999                          2400 ÷         8    = 300
                         ___ × ___          = ___                          ____ ÷ ___ = ____

                         ___ × ___          = ___                          ____ ÷ ___ = ____
