Matematika Swadana
In developed countries calculator to get an important role in the process
of learning mathematics. This is indicated by the use of calculators in
mathematics learning ranging from primary education to higher education. Not
only limited to that, research on the graphing calculator is indicated by the
number of journals, books, conference reports and dissertations that discuss
the graphing calculator. The importance of a calculator is to bridge the
arithmetic and algebra.
Types of calculators had great development. Judging from their use calculator consists of two types. This type consists of two kinds, namely plain calculator and a scientific calculator. Regular calculator is widely used in everyday life. According to this calculator, first signs of repressed more done. For example in the calculation of 2 + 4 x 8, according to the ordinary calculator 6 x 8 = 48.Yet according to the rules of mathematics, multiplication is completed first, so it should be 2 + (4 x 8) = 2 + 32 = 34. Meanwhile, scientific calculators are widely used by high school students, teachers, or students to assist counting function. Scientific calculator has a way of working that follow the rules work in mathematics. For example in the calculation of 2 + 4 x 8, according to a scientific calculator, multiplication is done first, so 2 + 4 x 8 = 2 + 32 = 34.

One example of a scientific calculator is a graphing calculator. Graphing
calculator has its own advantages than regular calculator. The advantage lies
in the ability of the calculator to solve math problems quickly and display
them in graphical form. Another advantage of the graphing calculator to create
a program that can solve math problems.
Benefits that can be explored from the use of calculators are:
- help in understanding math concepts,
- cause the student calculators work on the problems become easier
- the existence of calculators in the classroom to make lessons more interesting
- The calculator as a tool just count
- use the calculator to learn much more developed
- calculator to match the craftsmanship
- help to strengthen computational skills,
- develop a high-level thinking skills,
- increasing problem solving skills, and
- create a more realistic problem-solving.
