This math topic helps learners improve their ability to define the domain and range of functions by translating verbal descriptions into mathematical inequalities. It presents a focused exercise on understanding and representing real number constraints using inequality symbols, specifically without the use of union. There is a strong emphasis on correctly interpreting terms such as "all real numbers less than", "greater than or equal to", and "all real numbers" into proper inequality expressions. This forms part of introductory skills concerning function domain and range representation.
