Substitution
Calcpad can substitute the values of variables in all formulas in the output, just before the answer:
x1 = -b – √D2·a = -3 – √892·4 = -1.55
For that purpose, you need to check the "Substitution" checkbox at the bottom of the program window. That makes the results easy to review and check. This is important when calculations have to be checked by supervisors, teachers etc. This is also an advantage over the spreadsheet software where the actual formulas are hidden in the cells.
If you do not need the substitution, you can uncheck this option. Then the answers will follow directly the calculation formulas:
x1 = -b – √D2·a = -1.55
