-study chapter 4 arithmetic operators, relational operators, logical operators.
-buat exercise logical operator by group dan ade (5mark)
-study chapter 6 decision
-buat exercise by group if...else & switch case.
-miss memberi homework 6 exercise secara individu dan perlu dipostkn di dalam blog sendiri.

as usual credit goes to our leader Nas for this Weekly Reflection
