Key takeaway: Number and operations terms describe kinds of numbers and how to compute with them, from reciprocals and integers to irrational numbers, rational exponents and complex numbers.
These number and operations terms trace how the idea of a number grows through middle and high school: whole numbers and fractions, then negative numbers, then irrational numbers, and finally complex numbers. Along the way come the tools to compute with them, such as exponents, roots and the order of operations.
