DoMath $-$ Put all the code in the main method

The program will loop $4$ times and, in each iteration, it will prompt the user for $2$ integers with the prompts of "Enter num$1$: $"$ and "Enter num$2$: $".$ You can assume that the user will provide an integer for each prompt. In the first iteration, add the input, in the second, subtract them $($num$1-$ num$2),$ in the third iteration, multiply them, and in the final iteration divide $($num$1/$num$2).$ The output will be the four answers separated by a comma followed by a space. If num$2$ is zero when you do the division, the answer should be Error.

Sample run $($with user input in bold$)$

Enter num$1$: $10$

Enter num$2$: $20$

Enter num$1$: $30$

Enter num$2$: $40$

Enter num$1$: $7$

Enter num$2$: $8$

Enter num$1$: $10$

Enter num$2$: $0$

$30,-10,56,$ Error

Note: If the last input was $2,$ instead of $0,$ you would have a $5$ instead of Error in the output
