No one is "bad at math". Math is (mostly) logic and humans are innately logical (most of us anyway). You're only "bad at math" because you had/have a bad math teacher. A good math teacher will show you how easy it actually is. https://twitter.com/MBA_Iphone/status/1196202880870625280

Your math teacher may be very good at math, but that doesn't automatically translate to being a good math teacher. Teaching is a skill all it's own.
