I could count to 20 when I was two years old.
I could read at a fifth grade level when I was in kindergarten. At least that’s what my mom says my kindergarten teacher told her.
My senior year in high school I took AP Physics. We did an experiment on projectile motion.
The experiment used a spring-loaded cannon which would launch a metal ball. We were supposed to launch it through some hoops. We had to calculate the right heights for the hoops.
I did the math for our team. We finished first, and we were the only group to get it right the first time.
I could think of other examples, but I think those are sufficient.
