I am developing a video game focused on teaching math and I need to include in the scene a text that contains a question related to the topic and that the correct answer can be selected
Do you mean to have one scene capable of displaying any question?

yes, and answer options also appear
if you have any suggestions would be helpful too
The scene needs at least a RichTextLabel and a few Button nodes as children. You mentioned “focused on teaching math” so here’s an example.
var numbers : Array = []
var operation : int
var answer : float
var sum : String
func _new_question():
#set the sum length
var numberAmount = randi()%6+3
#get the numbers and operations
for i in numberAmount:
numbers.append(randi()%11+1)
#set the operation
operation = randi()%4+0
#write the first number
answer = numbers[0]
sum += str(numbers[0])
#write the rest of the sum
for num in numbers.size() - 1:
if operation == 0:
answer += numbers[num+1]
sum += "+"
elif operation == 1:
answer -= numbers[num+1]
sum += "-"
elif operation == 2:
answer *= numbers[num+1]
sum += "x"
elif operation == 3:
answer /= numbers[num+1]
sum += "÷"
sum += str(numbers[num+1])
#set the labels text as the sum
RichTextLabel.text = sum + "="
#get the child button nodes and make one the correct answer
var buttons = get_children()
var correctButton = randi()%buttons.size()+0
for ansOpt in buttons.size():
if ansOpt == correctButton:
buttons[ansOpt].text = str(answer)
else:
buttons[ansOpt].text = str(answer+rand_range(-10, 10))
This should give you a sum like 7+3+2= and a button with 12.
