Comments on: Would I write the addition and subtraction in the same algorithm or use branching? http://www.mathstudenthelp.info/subtraction/would-i-write-the-addition-and-subtraction-in-the-same-algorithm-or-use-branching-2 Let us help you add it up!

OR - do a loop of 10 for each of the 10 questions. - - get the 2 random numbers. - - then do a switch on the inputted operator. - - - according to which operator, generate the answer. - - end switch. - - ask the user to answer. - - compare the users answer to the generated answer. - - update the amount of correct answers if it is correct. - end loop. Then check the amount of correct answers to output the message of congratualtions or not. Good luck with it.<br><b>References : </b><br> What I would do after getting the input from the user as to what operator they want to use, and checking that the input is valid, is:

OR

- do a loop of 10 for each of the 10 questions.
- - get the 2 random numbers.
- - then do a switch on the inputted operator.
- - - according to which operator, generate the answer.
- - end switch.
- - ask the user to answer.
- - compare the users answer to the generated answer.
- - update the amount of correct answers if it is correct.
- end loop.

Then check the amount of correct answers to output the message of congratualtions or not.

Good luck with it.

I suppose if your random numbers can be either positive or negative, you could "accidentally" end up with either addition or subtraction, but it seems like you need to just create a conditional branch for each of the 5 operations.<br><b>References : </b><br> I can’t think of an obvious way of doing them both in the same routine.
