Program Matematika

Program matematika ini dibuat dengan menggunakan delphi.

Dimana ada 7 form di dalamnya, yaitu:

1. Form 1, untuk penempatan main menu

2. Form2, untuk program deret aritmatika

3. Form3, untuk program deret geometri

4. Form4, untuk program permutasi

5. Form5, untuk program kombinasi

6. Form6, untuk program balok

7. Form7, untuk program nilai akar kuadrat
