I'm trying to create this Math Quiz project where I construct a sprite to move around randomly ten times. In order to win, I want the users to have to touch the sprite at least 3 times while it moves randomly and answer three simple math questions and give the sum total at the end. Whenever the mouse pointer touches the sprite, I want the sprite to say one of three things: 1) Add (any random number ranging from -10 to 10), 2) subtract (any random number ranging from -10 to 10) or 3) multiply (any random number ranging from -5 to 5).

I want the Sprite to be able calculate the total after being touched by the mouse pointer and randomly assigning 3 random operations (add, subtract, or multiply a random number). When the user puts in the correct answer, I want the sprite to be able to tell the user if his/her answer is right or wrong. If right, I want the sprite to say, "Correct!" and ask the user to advance to the next level (I'd use broadcasting here I suppose?). If the user's answer is wrong, I want the sprite to say "Wrong! Try again!" and start all over again.

I'm having a lot of difficulty creating the correct variables for this and getting the sprite to follow these commands. If someone could give me the step-by-step commands for this, I would greatly appreciate it!

For the math problems, you could use something like this:

set [level v] to (1)
repeat until <(level) = (4)>
 if <(level) < (3)>//Picks the numbers for the problems.
  set [number v] to (pick random (-10) to (10))
  set [number2 v] to (pick random (-10) to (10))
 else
  set [number v] to (pick random (-5) to (5))
  set [number2 v] to (pick random (-5) to (5))
 end
 if <(level) = (1)>
  ask (join(join(join [What is ] (number)) [ + ]) (join (number2) [?])) and wait
  if <<(number) + (number2)> = (answer)>//Checks the answer.
    ask [Correct! Do you want to move on? (Y/N)] and wait
    if <(answer) = [Y]>
     change [level v] by (1)
    end
  else
   say [Wrong. Try again.]
  end
 else
  if <(level) = (2)>
   ask (join(join(join [What is ] (number)) [ - ]) (join (number2) [?])) and wait
   if <<(number) - (number2)> = (answer)>//Checks the answer.
    ask [Correct! Do you want to move on? (Y/N)] and wait
    if <(answer) = [Y]>
     change [level v] by (1)
    end
   else
    say [Wrong. Try again.]
   end
  else
   ask (join(join(join [What is ] (number)) [ x ]) (join (number2) [?])) and wait
   if <<(number) * (number2)> = (answer)>//Checks the answer.
    ask [Correct! Do you want to move on? (Y/N)] and wait
    if <(answer) = [Y]>
     change [level v] by (1)
    end
   else
    say [Wrong. Try again.]
   end
  end
 end
end

Sorry about only giving the script. If there's any part of it that you don't understand, just ask and I'll explain it.

Anyway, I hope that this helps!

Wow, this is very helpful, thank you SO much! I have one question, though. How do I get my sprite to ask these random math questions only when it is touched by the mouse pointer? Thank you!

This would require several changes, so again, sorry about only giving the script:

when gf clicked
set [level v] to (1)

if (touching [mouse pointer v]?)
set [number v] to (pick random (-10) to (10))//This is here to make the script work.
repeat until <(number) = [P]>
 if <(level) < (3)>//Picks the numbers for the problems.
  set [number v] to (pick random (-10) to (10))
  set [number2 v] to (pick random (-10) to (10))
 else
  set [number v] to (pick random (-5) to (5))
  set [number2 v] to (pick random (-5) to (5))
 end
 if <(level) = (1)>
  ask (join(join(join [What is ] (number)) [ + ]) (join (number2) [?])) and wait
  if <<(number) + (number2)> = (answer)>//Checks the answer.
    ask [Correct! Do you want to move on? (Y/N)] and wait
    if <(answer) = [Y]>
     change [level v] by (1)
     set [number v] to [P]
    end
  else
   say [Wrong. Try again.]
  end
 else
  if <(level) = (2)>
   ask (join(join(join [What is ] (number)) [ - ]) (join (number2) [?])) and wait
   if <<(number) - (number2)> = (answer)>//Checks the answer.
    ask [Correct! Do you want to move on? (Y/N)] and wait
    if <(answer) = [Y]>
     change [level v] by (1)
     set [number v] to [P]
    end
   else
    say [Wrong. Try again.]
   end
  else
   ask (join(join(join [What is ] (number)) [ x ]) (join (number2) [?])) and wait
   if <<(number) * (number2)> = (answer)>//Checks the answer.
    ask [Correct! Do you want to move on? (Y/N)] and wait
    if <(answer) = [Y]>
     change [level v] by (1)
     set [number v] to [P]
    end
   else
    say [Wrong. Try again.]
   end
  end
 end
end
end

I hope that this helps!

Need that forever.
