My apologies for misuse of terminology: Those two conditionals are the =
particular elements that I speak of.

Hi there,
I'm a relative newbie when it comes to scripting in ruby however, for a =
year 11 project at school, it is necesary for me to program a maths =
utilit which requests a user - elementary school aged - to add to =
numbers together to reach an answer. I've effected some coding however, =
I'm a little stumpt as to why the aplet is not correctly parsing through =
the loops.
=3D=3D=3Dscript extract starts=3D=3D
question =3D 1
unless question =3D=3D 20
 score =3D 0
 number_of_questions =3D 0=20
 num1 =3D rand(20)=20
 num2 =3D rand(20)=20
 correct_answer =3D num1 + num2
 puts("What is #{num1} + #{num2}/?")
 user_answer =3D gets.chomp!.to_i
 unless user_answer =3D=3D correct_answer
  puts("Sorry, that is not correct. Please try again.") =20
  user_answer =3D gets.chomp!.to_i
 end
 score +=3D 1
 number_of_questions +=3D 1
 question +=3D 1
 puts("Well done! That is correct.\nYou have answered #{score} out of =
#{number_of_questions} questions correctly.")
end
exit
=3D=3D=3Dscript extract ends=3D=3D=3D

  What loops?  I don't see any loops in there at all.  I see two =
conditionals ("unless question =3D=3D 20" and "unless user_answer =3D=3D =
correct_answer") but no loops.

  That might be a clue.

        The only reason some people get lost in thought is because it's =
unfamiliar territory. (Paul Fix) =20
