My homeschooled 13yr is doing Algebra II. He is advanced by 1 yr. in math. I can’t imagine him doing Calculus at this age.
You are slacking; algebra is easy and should be no trouble for a normal 10 year-old: as it is merely the extension of the basics of arithmetic with unknowns. Any marginally thoughtful individual could 'discover' algebra if they were trapped on a desert island and needed to manage supplies.
Calculus is a bit more of a mind-bender and ought to be taught young. Many of its rules are non-intuitive — like why should the area under the curve be related to the slope of the curve at that point? (Granted trig is a bear; but elsewise using calculus [after getting those non-intuitive rules down] is mostly just algebra.)
