I am trying to code a math tutor program that will have random numbers generated. Any suggestions would be greatful.

Output suppose to be:

I am having problems with this code. I keep switching it around and can not seem to get it right. This is what output suppose to be:

Menu of Operations

1. Addition

2. Subtraction

3. Multiplication

4. Quit.

Enter the number of the operation to try (1-4)? 2

What is 6 - 8 ? 2

No, the correct answer is: -2

Menu of Operations

1. Addition

2. Subtraction

3. Multiplication

4. Quit.

Enter the number of the operation to try (1-4)? 3

What is 3 x 4 ? 12

Yes, that is correct. Good job!

Menu of Operations

1. Addition

2. Subtraction

3. Multiplication

4. Quit.

Enter the number of the operation to try (1-4)? 6

(BEEP) Input value is out of range.

Enter the number of the operation to try (1-4)? 4
