For exercise "Understanding Decimals Place Value", for the given number (9722.127), the program does not accept the correct answer. When I click "show answer", it shows an incomplete answer (9000 + 700 + 20 + 2 + .1 + .02), omitting the final .007. Interestingly, when the full solution is displayed by repeatedly clicking on the "Show step" button, the full answer does appear including the .007 at the end. Oddly the script will accept neither of these answers (with and without the .007) as correct.

PS - I love the site, and I want to express how much I appreciate your work towards increasing the quality of education everywhere!
