Mathematical thinking is linked to subjects where mathematics can be productively applied. Studying applied mathematics will enhance learning and understanding of Physics, Chemistry, Economics, Accountancy and other Skill based subjects. Through this course students will learn problem solving, reasoning and proving, reflecting, selecting tools and computational strategies, connecting, representing and communicating mathematical thinking.
