Question
In this assignment, you play with variables, arithmeticoperators and random numbers.
You should set up your program to use input, output, and randomnumbers. Give a short introduction and then start the programby selecting two random numbers and show them with as an additionproblem
3 + 7 =
Then ask the user to input an answer, and then display theanswer. Then do the same with subtraction, multiplication, anddivision. Don’t worry yet about whether the user got thecorrect answer yet. Each problem should have 2 randomnumbers to add or subtract. Be sure to set your random numberin such a way that you will not get a 0 for division. Divisionby 0 would be bad.
