So i want to the person to do multiple answers but how to do from here?

when green flag clicked
say [] for (2) secs
if <(answer) = [ ]> then
    say [hi] for (2) secs
end

Put it in a forever loop for multiple questions and answers. Here is an example of a simple math game I made for with my students. But you can't use a say block along with the answer block. You need to use the Ask block found in sensing.

Or in the case of this project the user has 3 attempts to correctly answer the question.

when green flag clicked
say [] for (2) secs
ask [] and wait    // otherwise 'answer' won't contain anything useful!
if <(answer) = [ ]> then
    say [A] for (2) secs
else
if <(answer) = [ ]> then
    say [B] for (2) secs
else
if <(answer) = [ ]> then
    say [C] for (2) secs
end

and so on

is it possible to combine multiple answers together

EX: answer 1 is 9
answer 2 is 5
then combine them like result is 95

Yes by using the join block.

(join (answer_1) (answer_2))

But in the future instead of digging up a topic from 2016 it would be best if you created a new topic so we can help. They refer to digging up and replying to old topics necroposting, and that is discouraged on these forums.
