The Quizes are insane

Question

it's not programming . it's math . plain math .. I can just get a calculator and everything is solved how am I supposed to do sins and cosine in that small amount of time . who else think they should remove these math quizzes from solo learn ?

Answer 1

To be honest i like them, it is a fun way to keep fresh my mind, also if after some days quizzes should be different, otherwise it is pretty easy memorize all answers. ;)

Post Scriptum - Often the quiz seems to be hard, but trust me, there is always an "hidden trick" to solve it in less than 5/6 seconds. Copy and paste it in your CodePlayground and try to figure out the issue.
