 # What Color Is That Square?
 
-Positions on a chess board are identified by a letter and a number. 
+Positions on a chess board are identified by a letter and a number.  
 The letter identifies the column, while the number identifies the row, as shown below:

-Write a program that reads a position from the user. 
-Use an if statement to determine if the column begins with a black square or a white square. 
+Write a program that reads a position from the user.  
+Use an if statement to determine **if the column begins with a black square or a white square**.  
 Then use modular arithmetic to report the color of the square in that row. 
-For example, if the user enters a1 then your program should report that the square is black. 
-If the user enters d5 then your program should report that the square is white. 
 Your program may assume that a valid position will always be entered. 
 It does not need to perform any error checking.
 
+Example:  
+Input =  a1  
+Output = black
+
+Input = d5  
+Output = white
