### RUMUS CEPAT DALAM PEMBELAJARAN MATEMATIKA, MALAIKAT ATAU SETAN?

#### Abstract

*This paper discusses differences in people's perspectives on the use of fast formulas in mathematics. Some people argue that the use of fast formulas can increase student motivation in learning, and help students in examinations. **Fast** formulas can help students improve their learning achievements. The fast formula is also very helpful for students in taking college entrance exams. For them the presence of a fast formula is like a helping angel. However, some people argue otherwise. The fast formula is considered to damage the basic concepts that have been built in the school. The fast formula is also seen to reduce the credibility of the teachers. The fast formula can lead students if they are not careful in using it. Even a fast formula can obscure the quality of the results of the exam so that the exam no longer reflects the true abilities of students. The existence of a formula can quickly become a stain in the education system. For them, the existence of a fast formula is like a sweet-faced demon, but it is misleading. This paper examines the nature of the existence of the fast formula, starting from the reason why the fast formula was created, how fast formula was obtained, how the nature of the fast formula, and how fast formula should be used so that it can contribute to improving the quality of mathematics education. Thus the community will look at the fast formula from the right perspective so that it can take its positive benefits and avoid the adverse effects that might result from it.*
