                    Lesson 1

                                                                                                                                                                          

                                                            Problem:                   Simplify: i64 + i80 + i50

                                                            Solution                    If 64 is divided by 4, the remainder is 0 - the value is 1

                           Step 1:  

                     

                                                                                Solution                          If 80 is divided by 4, the remainder is 0 - the value is 1

Step 2:                        

 

                                                                                Solution                           If 50 is divided by 4, the remainder is 2 - the value is -1

                           Step 3:           

                                                                                                (1) + (1) + (-1) = 1

 

                                                             Solution                    The answer is:  1

 Step 4:
