Answers to Questions
How to make a formal calculation?
dCode brings you a formal calculator which authorizes all calculations and answer an exact result (non-approximate) with the most simplification possible.
Example: $$ x^2-(x-1)(x+2)+2x = x+2 $$
Example: $$ x+1+x-2 = 2x-1 $$
dCode gives also an equation solver, derivatives, primitives, etc.
