*Using the four digit numbers students must use three arithmetic symbol to find the maximum and minimum value, such as (*, -, +), (+,+,*),(*,*,:), etc

*They have time three minute to do it

*When the time is over they must presentation their result to their friend, and then write the way to write board

Form The Instrument    : question

The Result :

1.Ahsani Takwim





     Maximum Value : 2*3*3*2 = 36

     Minimum Value  : 2 – (3*3*2) = - 16

2.Alex Sandra





    Maximum Value : 5*6*1*2 = 60

  Minimum Value  : 1 – (6 *5*2) = - 59

3.Dinal ‘Ulya





   Maximum Value : 4*6*2*1 = 48

  Minimum Value  : (1-2)*(4*6) = - 24

4.Fini Mulyani





   Maximum Value : 3*4*4*3 = 144

  Minimum Value  : (3-4) * (4*3) = -12

 Let try to your self. Do you get the Biggest value in maximum and the smallest value in minimum ? Enjoy the game....
