Builds a working calculator-like app that runs across classic NeXTSTEP/OS X releases and demonstrates it actually solves expressions with order of operations, parentheses and carryover; shows Project Builder debugging, breakpoints and fat-binary choices; implements syntax detection with regular expressions and arithmetic with NSDecimalNumber, NSAttributedString, NSTextAttachment, NSTextView; reveals manual memory work with manual retain and release but confirms it compiles and debugs in modern Xcode.
