adding scientific keyboard

[Ripandas]

As I am a science student and during my online study I have to use lots of scientific sign like alpha, beta etc. But I don't put these sign in chat. So can I install scientific keyboard or these Mathematical characters? There is any apk or app in galaxy store for these problem.
