# Solution Below
num1 = 8
num2 = 3

sum = num1 + num2
difference = num1 - num2
quotient = num1.to_f / num2.to_f
product = num1 * num2
modulus = num1 % num2





# RSpec Tests. They are included in this file because the local variables you are creating are not accessible across files. If we try to run these files as a separate file per normal operation, the local variable checks will return nil.
