In daily life, people are always having problems. The problem has many solutions or a solution only to solve it. In learning mathematics, there is open-ended problem that is also a problem that has many ways of solving. Polya (1973) argues that there are four steps in solving the problem. They are: (1) understand the problem (understanding the problem), (2) make a plan (devising a plan), (3) implementation (carrying out the plan), (4) re-examine (looking back). By seeing the results of several studies suggest that the ability level of students affect the process of solving math problems. Based on this background then, the problem that also the focus of this research was "How the profiles of the problem solving mathematical junior open class VIII student based on his mathematical abilities?."

Matematika dan bahasa merupakan dua ilmu yang sangat berbeda satu sama lain. Walaupun demikian pada dasarnya matematika sama dengan bahasa, didalam keduanya berisi tentang kalimat. Dalam ilmu bahasa kalimat adalah serangkaian kata-kata yang terbentuk dan memiliki makna.Tidak jauh berbeda dengan matematika, di dalam matematika juga terdapat kalimat matematika yang merupakan suatu rangkaian kata atau simbol yang bernilai benar dan salah.Dalam penyusunan kalimat tersebut matematika dan bahasa memiliki aturan dalam penulisan.Ilmu bahasa memiliki aturan dalam pemilihan kata-kata yang sesuai untuk membentuk suatu kalimat yang memiliki arti.Sedangkan matematika juga memiliki aturan tertentu dalam menyusun suatu kalimat.Di dalam kalimat matematika tersebut berisi serangkaian kata/simbol yang beraturan yang memiliki makna. Sama halnya dengan bahasa, jika dalam penyusunan kaliamat tersebut tidak menggunakan kata-kata yang sesuai maka kalimat tersebut akan memiliki makna yang salah. Begitu juga dalam matematika jika dalam penggunaan aturan simbol tidak ditaati maka kalimat matematika itu akan bermakna salah.Berdasarkan pada hasil observasi yang dilakukan pada mahasiswa UMM Semester VI kelas B dengan jumlah mahasiswa sebanyak 50 orang. Terdapat beberapa kesalahan penggunaan simbol dalam menyeselsaikan suatu permasalahan matematika.Berdasarkan data awal yang dikumpulkan dapat disimpulkan bahwa mahasiswa banyak melakukan kesalahan dalam penulisan pendefinisian fungsi. 40 mahasiswa melakukan kesalahan dalam penulisan/peletakan simbol sama dengan â=â dan 30 mahasiswa melakukan kesalahan dalam penulisan/peletakan tanda bagi ââ. Dibutuhkan suatu upaya dalam mengatasi kesalahanyang dilakukan oleh mahasiswa.Dengan menggunakan Maple, mahasiswa dibimbing untuk belajar menuliskan symbol/notasi matematika dengan benar.Â Kata Kunci:maple, konsep, simbol.
