How do I create random math problems

Hey guys im designing my first game!! been wanting to do this for a long time for my kids. This game is a platformer that you have to collect coins. they are inside chests. To open the chect you have to answer a random math question. My problem is that I cannot seem to create a random question. Im probably doing it all wrong but could someone point me in the right direction? thanks in advance.

This is what ive been trying in a text field

round(random(0,10)) " + " round(random(0,11)) " ="

says there is a syntax error with the " + "

what would be the best way of achieving what i want?

I would also like to know how you guys would handle the answering of these questions. Do i put a text box in and do a function to compare the values, then tell it to move on with the game?

It should be:

round(random(0,10)) & " + " & round(random(0,11)) & " ="

Don't forget to put & to concatenate the strings

thank you very much. ill remember that for next time. Its been so much fun learning this. How would you setup the answering of the question? I would like the player to put the answer in a text box and it would check it its correct when the button is pressed.

Hey guys, still having issues with this. I followed the tutorial from scirra.com/tutorials/4810/math-quiz-simple-equation. But cant seem to get the text to display. Can someone please tell me what im doing wrong. Ive attatched the capx file below

I'm looking at your capx, I will try to look at your problem.

I found your problem You just forgot to include the event sheet where your function Create is written.

thank you soooo much!! This is something i didnt know. I knew it would be something simple. Thanks again
