+# Suppose a = "4"
+# Then if we write print(a+2) expecting it to print 6, but instead it prints 42. That's because It converts 2 to a string and then concatenates it to "4" which is a string.
+# Try to google these fancy words like concatenation and ofcourse we're always there for you.
+
+#So what we do is to convert a from string to an int
+#that's done by a = (int)(a)
