    Simple app that remembers all my work equations. -1 star for save/load and variable bugs + no explanation of file preferences.

    Ben kullanmaya başladım başlangıçta biraz zorlandım ama çözdüm. a b sütünlarına değerleri yazıyorsunuz. en üst satıra değerleri ifade eden harfleri yazarak formülize ediyorsunuz. ve = bastığınız anda sonuç elinizde... basit uygulama

    Has potential. Not easy to edit variables, a bit touchy and too many steps to name a variable. Should be able to use a variable within variables.
