> math is thought to be 'scary' and 'hard'

> Plenty of video games are known to be scary and hard

Those statements seem related because of the ambiguous definition of "scary". In relation to math, "scary" causes anxiety, whereas in relation to video games, "scary" causes excitement.

As soon as you grasp the different meanings, you can clearly see that even though both statements are about the same word they are still orthogonal.
