 # Problem Statement-3.
 
 
 ***
 ### Make a calculator with GUI
 
+Hello
+I’m Chetan Chinchulkar from IITG
+
+This video is regarding problem statement 3 under GameOfCodes. GameOfCodes Python is a coding competition based on Python problem statements.
+Problem statement 3 is Calculator with GUI using Python
+
+There are two versions of the calculator :
+Standard calculator
+Bsic mathemcatival operations are available
+Scientific calculator
+Advanced mathematical operations like trigometric functions,exponential etc are added
+
+In addition to this, it has Rand button to randomly generate and show any random number. This also has Signum function.
+
+Error Handling
+The GUI takes care of varies error by correspondingly displaying error messages.
+
+Uniqueness of this calculator is copying the result, and also has age calculator
