Adding to a variable

I’m thinking I am doing this the hard way so I’m hoping someone can point me in the right direction.

I’m doing a simple game that keeps a score. The way I have it set up right now I assign a varaible for each question and depending on how they answer a score is assigned (i.e. q1score, q2score, q3score). There is a total score box that keeps a running tally of the score.

Right now the total score is totalscore=q1score+q2score+q3score

I’m thinking I’m missing some sort of easy command to just add to the totalscore variable instead. So in other words when they select the correct answer it adds (ex. 10 points) to the totalscore.

I just can’t seem to find the right syntax anywhere. Is there something that will do this like a “totalscore +10” type of command?
