CalcNote - Notepad Calculator on Windows Pc

Type a calculation like a note and the answer appears instantly. No equals button.
Write many calculations on one screen, mix text with math, and edit any line at any time.
CalcNote is a notepad calculator that combines the ease of a calculator with the power of a spreadsheet.

Example: comparing prices while shopping

Shop A
USD 18 * 2 items + USD 4 (shipping)

Shop B
USD 19 * 2 items (free shipping) + 8% (sales tax)

Shop C
USD 18.30 * 2 items + USD 5 (shipping) - USD 2 (points)

Because notes and math live together, every calculation still makes sense when you read it later. Save your work as files, print it, or share it by email.
