Change the line

    result = "Sorry...you were wrong.

in your script to

        result = "Sorry...you were wrong. Expected {!r}, but got {!r}".format(answer, response)

and find out yourself.

Hint: answer in the makeproblem() function is not a global variable.

The first argument of the Text.insert() is a string in a special format. Read

http://infohost.nmt.edu/tcc/help/pubs/tkinter/web/text-methods.html

for the details. You have a mix of one float (which may work by accident) or two integers (which raises an exception).

I don't know, and I'm too lazy to google ;)

The score variable is not declared global and not initialised. You cannot increment something that doesn't exist.
