In the US it’s common to give students “word problems” that describe a scenario and ask them to answer a question that requires applying whatever math they’re studying at the time. Students hate them and criticize the problems for being unrealistic, but I think they really just hate word problems because because they find them difficult. To me that means they need more word problems so they can actually get used to thinking about how math relates to the real world.
Based on what others in the thread are saying, that’s already covered for free by the key fob. What they’re charging for is doing it through the internet.
Question for the audience: what city do you most associate this style with? For me it’s Seattle, because that’s where I live, and ugh, it’s everywhere.
