Quantitative reasoning is hard for humans and it is hard for computers. Google’s new model just got astonishing results in solving math problems.image from Michal Matlon at unsplash.comWe are used now to language models such as GPT-3, but in general, their output is textual. Quantitative reasoning is difficult (many of us still have nightmares about calculus from the university). It is hard also for language models, where their performances are far from reaching human-level performance. Solving mathematical or scientific…

Creating and grading tests is one of the most time-consuming tasks teachers need to deal with. In Vietnam, a startup called Azota wants to help with an online software platform that not only helps educators develop and proctor tests, but also automatically grades them using information from Vietnamese teaching materials.
