print "We can just give the function numbers directly:"

print "OR,we can use variables from our script:"
amount_of_cheese =10
amount_of_crackers = 50
cheese_and_crackers(amount_of_cheese, amount_of_crackers)

print "We can even do math inside too:"
cheese_and_crackers(10+20, 5+6)

print "And we can combine the two, variables and math:"
cheese_and_crackers (amount_of_cheese+100, amount_of_crackers+1000)
