Decimals, Fractions, and Percents
Once students have mastered addition, subtraction, multiplication, and division, they move on to other mathematical concepts such as how to work with decimals, fractions, and percents, as well as negative numbers and absolute value; however, a great number of all of the other mathematical concepts they will learn in the rest of their academic careers all depend on a solid foundational understanding of basic arithmetic, so it is absolutely crucial that students clearly understand the concepts and do not unwittingly misunderstand them, as such misunderstandings can derail later attempts to learn about more difficult math.
