Science Spoon Problem Report
Please report any problematic problem* below, and we'll get it fixed.
* We imported from the original NSB PDFs, but PDFs are hard to parse. Exponents, fractions, subscripts, and even minus signs didn't come across well. While we've updated thousands of questions, with over 10,000 imported, we've likely missed some issues. Reporting helps us clean up the last few questions that we haven't found.
