abstract objects, concepts and principles are tiered, and the procedure for manipulating many forms turns out to cause difficulties in learning mathematics. Here are some of the causes of mathematics learning difficulties that are often experienced by students:

1. Facts

Facts are agreements or agreements made in mathematics, for example symbols, names, terms and agreements. The difficulty is often experienced by students because mathematics is full of symbols or symbols, as well as foreign terms in their ears, This is certainly very contradictory to the thoughts of most of us who are accustomed to thinking about concrete objects.

2. Concept

Concept Is an abstract understanding that allows a person to classify objects or events. In the cognitive aspect is an aspect related to reason or thought process, namely the ability and activity of the brain to develop rational abilities. In the cognitive aspect includes the knowledge that refers to the ability to remember the material that has been learned from the beginning to the end. Students lack understanding of the concept of each material correctly, and the ability to remember the concept of processes, methods and structures is less accurate. So, in every workmanship the students feel difficulties because of the lack of mastery of the material and the processes / steps that must be done in each answer to the question.

3. Principle

Principle That is a statement that states the validity of a relationship between several concepts. The statement can state the characteristics of a concept, or the laws that apply to the concept.

4. Skill

Skills are procedures for speeding up workmanship, but are still based on correct logic.

The relationship in mathematics learning difficulties is students who are slow in using operations and procedures, it will hamper the work of their ability to solve mathematics.
