In some countries, calculators are one of the important things in teaching learning process for Mathematics learning. This is shown with used of calculators from elementary school until senior high school. They used calculators to make visualization figure of the graph. So they will know the real figure of the function. Besides that, calculator used to make easier in counting. The students usually used scientific calculators because it easy to operate Mathematics with it. One of the scientific calculators is graph calculators. Graph calculators has feature to show the result of Mathematics problem faster and equipped with its graph. The other superiority of graph calculator is to make program that can solve Mathematics problem.

The students in SMK Muhammadiyah IV Yogyakarta have responds positive with used of calculators. With calculator they can solve Mathematics problem easily and more interested than before. But there are some constraints to used calculators. Sometimes, students difficult to understand the question that will be enter to calculators. They feel difficult to enter data in calculators. They feel difficult to interpret, analyze and make conclusion with the result of calculators. So, they should ask to their teachers.

Using calculators have many benefits, but there are bad effects to students too. Students become lazy to find the result manually. Students are too dependent on the use of calculators. Sometimes, uses of calculators are good and sometimes it can be make students become lazy to find the results by themselves.
