Request help personal calculator app

This may be a simple app to build, but to someone with no app building experience i don't know where to start. I've looked at some of the free app builder web sites but I couldn't find one that would do what I want.

I want to make a calculator app that has a pre-defined equation with a input value and the app will calculate the answer. I'm a self taught excel user so I can code a cell in Excel to do that, but I don't know how to build an Android app to do that .

Input X (doller amt)

Formula 1
((X-3.1)/0.45)x0.125=milage

Formula 2
(((X-3.1)/0.45)x0.4)+3.1= OTS ( new fare amt)

Title - "My OTS Calculator"
[ Calculator entry field]
below in smaller font-" enter meterd fare"
Standard 10 key but instead of an "=" a bar that says "calculate"

When enter the meter fare in the calculator entry field , then press calculate, the calculator 10 key disappears and is replaced by
Value milage + " mi"
Value OTS (format $###. ##) + OTS Fare
Below that two buttons "NEW" & "EXIT"

NEW, restarts the app with the calculator entry field erased
Exit, exits the app

I want to make that. Help me please!



Thanks
Angelo
