Returning functions for a math game
You are building an educational math game where the player enters a math term, and your program returns a function that matches that term. For instance, if the user types "add", your program returns a function that adds two numbers. So far you've only implemented the "add" function. Now you want to include a "subtract" function.

- Define the
subtract()function. It should take two arguments and return the first argument minus the second argument.

def create_math_function(func_name):
if func_name == 'add':
def add(a, b):
return a + b
return add
elif func_name == 'subtract':
# Define the subtract() function

return subtract
else:
print("I don't know that one")
add = create_math_function('add')
print('5 + 2 = {}'.format(add(5, 2)))
subtract = create_math_function('subtract')
print('5 - 2 = {}'.format(subtract(5, 2)))
