+# The program should have support for these four operations: addition, subtraction, multiplication, and division.
+# The program should accept both the name (add) and the symbol (+) for each possible operation.
+# Optional Enhancements
+# Print out the formula in addition to the result, i.e. 2 + 2 = 4
+# Add support for computing exponents (2^4 = 2 * 2 * 2 * 2 = 16).
+# Add support for the modulo operator (10 % 3 = 1).
+# Gracefully handle unexpected user input:
+# What happens if the user input is nil (i.e., the user just pressed enter)?
+# What happens if the user tries to add hotdog to elephant?
+# Make your program know when it needs to return an integer versus a float.
+# Add support for parentheticals, i.e. 10 / (5 + 5) = 1.
