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.
