Let’s count number 43 on abacus.

                  43 = three ones and four tens.

                  Therefore, the number is represented by three beads on the first wire of the

                  abacus and by four beads on the second wire.




                                            1

                                            10

                                            100
                                            1, 000
                                            10, 000

                                            100,000

                                            1, 000,000
                                            10,000,000

                                            100,000,000
                                            1, 000,000,000





                  Now try yourself and guess which number is shown in the given abacus.
