Text for math equations

Hi! I use blender to make youtube videos to explain physics visually. Sometimes I need to show equations to explain some phenomena. But unfortunately I can't type math equations in blender. All I want is that the blender support math text which includes all kinds of symbols. I don't specifically need a math editor. I can just copy the equations from another external math editor and paste it in the text field. It would be great if it is extended to geometry nodes but that isn't necessary.

Thanks!
