innerHTML returns a string. Trying to apply division in string results in NaN (Not a number). The correct way is to use Number.parseInt(n) for division instead. https://www.sololearn.com/post/115377/?ref=app https://www.sololearn.com/post/115762/?ref=app https://code.sololearn.com/WKKkpq0efxai/?ref=app
