Scientific Calculator- Simple &Multi Functions APK

many powerful features  for engineering

scientific calculator fx designed with many powerful features  for engineering . Some of these can greatly reduce the effort to solve problems, while others can be abused in interesting and fun ways. Being able to use these features can also be helpful for students on tests and exams where scientific calculators are allowed but more powerful graphing calculators are not.
