Kant- Math

"I shall confine my assertion to pure mathematics, they very concept of which implies that it contains pure a priori and not empirical cognition." -pg. 11

If I am reading this right, I think Kant is saying that math is a priori and if priori means not learning from experience.  I would have to disagree with Kant on this one.  We learn math from others.  We learn it by someone teaching us how to add and subtract.  By going to school and listening to our teachers we are learning by experience.  I'm not sure if that was what he was getting at but that's what I got out of it.

Please tell me what you think.
