I was very different. I learned basic addition as a toddler, and then demanded that my uncle teach me whatever was "next". Bless his heart, he made me a basic math game on his commodore 64 with flashing lights, progressively harder levels, time limits and hints. Through his patient instruction and a lot of free time on that game, I learned to multiply before entering elementary school and passed a college calculus class before entering high school. Then, somehow after going to high school I got really into sports and less nerdy subjects and never progressed much further in terms of math than where I was at the age of 14 or 15. I regret it and OpenCourseWare beckons.
