Subtraction of lengths

               Learning Objective – Students will be able to learn about subtraction of lengths.

               Explanation

               Subtraction of lengths
               Arrange the number in column according to the units. First subtract smaller unit then add larger
               unit. Then subtract like normal numbers.
               Example 1:                                      Example 2:
                                                  a)  Subtract  18m                       25cm  from  37m
                             m        cm                                km        m
                                              31cm               b)                       Subtract  54km  428
                            37        31
                                              m from 84 km 606 m         84      606
                          -   18      25
                                                                      -  54      428
                         =   19       06                              =  30      178










               Learning Outcome – Students are able to learn about subtraction of lengths.
