Perhaps it would have been more understood, if you had said it once, without the math. Not understanding the entire text appears to often trigger doubts on wheter one understands parts of it.

I noticed when I studied economic history that the pretty meaningless economics equations attached in the margins got students with a non-math background uncertain if they had understood the description of rise and fall of industries in the 19th century. Once they knew it was nonsense that could not possible appear on any exam (because I told them as much) and ignored it, the uncertainty went away.
