We expect a kind of understanding from students of Grade 3 of the National Curriculum. The fellow student should understand the number system and related operations. There are some relationships exist in between number systems of various types. We often come across four different number system in computer Science. For the class works and mathematical operations of Grade 4 we restrict our discussion to decimal system only.
