my arithmetic and algebraic skill, improved after trying to learn drawing. - Doing multiple operations at once without writing down the intermediate reault. - Operations on larger expressions with more terms. - Basic operations on more digits. I basically didn't do much maths for a year, but improved by a 40%+ by practicing something seemingly unrelated.
