They are effective in terms of both cost and benefit. Concrete models are concrete objects that describe real-world information. They positively affect the performance of students on math problems.Place value is an important math concept for early elementary students to understand. They have to learn that the value of a digit depends on its place in a number. For example, students should understand that in the number 142, the digit 1 has a value of 1 hundred. The digit 4 has a value of 4 tens, and the digit 2 has a value of 2 ones.

The methods used to model concrete objectives can involve models based on linear combination, statistics, machine learning, and physics. In the realm of optimization, mathematical programming and metaheuristic search methods are commonly used. This review also highlighted future directions of research in this field.

Concrete Mathematics: A Foundation for Computer Science, by Ronald Graham, Donald Knuth, and Oren Patashnik, first published in 1989, is a textbook that is widely used in computer-science departments as a substantive but light-hearted treatment of the analysis of algorithms.
